Tomatoes slide, potatoes roll, onions do both while making you cry - the batch-cooking staples are, almost without exception, annoying to slice by hand. They are also the vegetables that benefit most from uniformity: even tomato slices roast evenly, even potato slices cook through at the same rate. An onion holder slicer handles the whole awkward family: the stainless guide holds onions steady, and your onion holder slicer works on tomatoes and potatoes too, keeping slices even across all of them. For fitness fans prepping sunday batch-cooking sessions, that versatility matters - one tool steadies nearly everything you slice in volume. The 11 ideas below lean on these staples because they are cheap, filling, and endlessly flexible. This tool makes them fast and safe to prepare.
Sunday Batch Cooking Start at the Cutting Board
Every sunday batch-cooking sessions session begins the same way: vegetables meeting the board. How that first phase goes sets the tone - smooth, fast chopping builds momentum; sketchy, slow slicing drains it before the cooking even starts. It tips that phase toward momentum: onions held steady, slices coming off even, fingers protected throughout. For Fitness Fans, the cutting board is where the week's cooking is won or lost. The onion holder slicer makes sure it is won.
Gear That Pulls Its Weight
Every tool below solves a real weekly annoyance, An onion holder slicer included - onion holder slicer ends the rolling-onion era for good. The others:
- a salad spinner - rounds out a prep station nicely: it on the vegetables, this one everywhere else.
- a twist chicken shredder - the kind of supporting tool you reach for weekly without thinking about it.
- a meat fat trimmer - because the best prep gear is the kind you stop noticing - it just works, week after week.
- a mini food chopper - a sensible companion for the jobs at the cutting board the onion holder slicer was never meant to do.
- a dumpling press - keeps the workflow moving on low-energy prep days when everything needs to be easy.
1. Cook a Big Pot of Grains
Grains are the backbone of a prep week: rice, quinoa, farro, or barley cooked in bulk on Sunday become the base for countless meals. Cook more than you think you need — grains are cheap and endlessly versatile. Cool quickly, portion, and refrigerate; most keep five days. An onion holder slicer earns its place in any chopping-heavy session: steady the onion, slice evenly, keep every fingertip intact. Press the prongs in and it guards your fingers while you slice confidently. Fitness fans appreciate the macro control here — portion it once and the numbers stay consistent all week.
2. Roast a Tray of Vegetables
One sheet pan, 425°F, twenty-five minutes — and you have the vegetable component for the entire week. Broccoli, cauliflower, carrots, Brussels sprouts, sweet potato: cut uniformly, toss in oil and salt, roast until the edges caramelize. Roasted vegetables reheat well and work in bowls, wraps, pastas, and salads. Uneven cuts cook unevenly; an onion holder slicer keeps slices uniform so the whole tray finishes at the same time. Batch slicing stays safe when this tool keeps fingers behind the guard.
The Wednesday test is the only one that matters: does roast a tray of vegetables still taste good midweek? Even cuts help more than people realize - uniformly sliced vegetables cook at the same rate and keep their texture in storage. That uniformity comes from your onion holder slicer, which keeps every slice the same thickness. Small detail, noticeable difference, all week long.
3. Portion Nuts and Trail Mix
Nuts are the perfect prep snack — protein, healthy fats, zero preparation — but the bag is a portion-control disaster. Divide into small bags or containers: a week's worth of sensible portions in ten minutes. Add dried fruit and dark chocolate chips for trail mix.Post-workout nutrition gets effortless when the food is already portioned and waiting.
The beauty of portion nuts and trail mix is how it scales - halve it for one, double it for the household, and the method never changes. More portions mean more slicing, which means the holder earns its keep even faster at scale. This tool keeps the rhythm steady whether it is two onions or ten. Scale the food; keep the fingers.
4. Cook a Pot of Beans
Dried beans cost pennies, taste better than canned, and cook themselves while you do other prep. A pound of black beans or chickpeas simmered with aromatics yields a week's worth of protein-rich additions for bowls, salads, and tacos. They keep five days refrigerated.
5. Prep Breakfast Components
Breakfast deserves its own prep slot: portion oats, bake egg cups, mix pancake batter (dry ingredients), chop fruit. Fifteen focused minutes eliminates five mornings of decisions. The components combine into different breakfasts, so nobody gets bored.
If you are new to prepping, prep breakfast components is an ideal first project: simple steps, familiar ingredients, and food you will actually eat. Beginners should learn the safety rule early: steady the food, guard the fingers. Your onion holder slicer teaches both at once - the prongs hold the onion while your hand stays behind the stainless guard. It is the rare safety upgrade that also makes you faster.
6. Hard-Boil a Dozen Eggs
Twelve eggs, boiling water, eleven minutes, ice bath — and you have the most versatile protein in the prep game. Snacks, salads, breakfasts, grain bowls: hard-boiled eggs improve all of them. They keep a full week refrigerated in their shells.
7. Set Up a Use-First Bin
Designate one fridge bin for foods that need eating soon — the half onion, the wilting herbs, the yogurt nearing its date. When it's time to cook, shop the bin first. This simple system cuts food waste dramatically with zero extra effort. Review it midweek and plan around what you find. When the slicing list is long, an onion holder slicer keeps the rhythm going - confident cuts, even slices, guarded fingers. With this tool holding it steady, the onion stops rolling and the slicing speeds up.
Cost is the quiet superpower of set up a use-first bin: humble vegetables, generous yield, and every portion replaces a bought meal. Even slicing protects those economics - uniform pieces mean nothing burns and nothing stays raw, so less food gets wasted. It keeps the cuts consistent with zero extra skill, so the savings never leak out through sloppy knife work.
8. Build Salad Jars
Dressing on the bottom, hearty vegetables in the middle, greens on top — the layered jar keeps every component pristine until you're ready to shake and eat. Five jars, thirty minutes, and lunch is handled. They hold four to five days refrigerated. Meal prep means serious onion volume; an onion holder slicer holds each one steady while you work through the bag. Even slices start with steady food, and this tool keeps every cut uniform.
Time is the real currency of meal prep, and build salad jars spends it wisely - mostly hands-off cooking while you do other things. The active minutes are mostly slicing, and steady food slices fast: no repositioning, no careful negotiation with a rolling onion. It removes the wobble, and confident cuts are quick cuts. Fast board work, fast session, fast week.
9. Roast a Whole Chicken
One roasted chicken is secretly three meals: sliced breast for bowls, shredded thigh meat for tacos, and a carcass for stock. It's the most economical protein in the prep world and the most flavorful. Roast Sunday, portion immediately, and the week is set. Keep an onion holder slicer at the cutting board and the slicing flies - no rolling, no wobble, no careful negotiation with the vegetable. Confident cuts are fast cuts, and the onion holder slicer makes every cut confident.
10. Marinate for the Week
Proteins marinate while you do everything else. Bag chicken in yogurt-herb marinade, tofu in soy-ginger, pork in citrus-chili — refrigerate, and cook fresh through the week or freeze for later. Marinating is passive flavor that costs you two minutes.For those tracking protein, this one makes hitting daily targets nearly automatic.
11. Wash and Chop Produce
The single highest-leverage prep job: wash the greens, chop the vegetables, slice the fruit. Prepped produce gets eaten; whole produce wilts in the drawer. It takes thirty minutes and transforms your fridge from a storage unit into a salad bar. Store greens with a paper towel to absorb moisture. An onion holder slicer works on tomatoes and potatoes too, so the whole awkward family of round vegetables gets the same steady treatment. The stainless guide of it holds firm while your own knife does the work.

What's the cheapest way to start meal prepping?
Start with ingredients you already buy: rice, oats, eggs, frozen vegetables, and whatever protein is on sale. You don't need new containers on day one — reuse what you have.

Buy staples in bulk, cook in volume, and let the routine fund itself.
