Meal prep doesn't mean eating cold chicken and broccoli for 7 days. It means cooking the building blocks once, then assembling 5-minute meals all week.
Why meal prep changes everything
When healthy food is the easiest option in your fridge, you eat it. When it's a decision at 7 p.m. after a long day, you order takeout. Meal prep removes the decision.
It also saves money, time and the daily "what's for dinner?" tax on your brain.
The 90-minute prep system
- 0–10 min: Wash and chop all vegetables.
- 10–40 min: Roast trays of veg + protein in the oven.
- 40–60 min: Cook one big pot of grain (rice, quinoa, oats).
- 60–75 min: Make one sauce or dressing.
- 75–90 min: Portion, cool, and store.
A simple shopping list framework
Each week, pick one from each category:
- 2 proteins: chicken, salmon, tofu, eggs, lentils, chickpeas
- 1 grain: quinoa, brown rice, oats, whole-grain pasta
- 3 vegetables: mix roasted + raw + leafy greens
- 1 healthy fat: avocado, olive oil, nuts, seeds
- 1 sauce: tahini-lemon, pesto, salsa, yogurt-herb
Batch-cook the right components
Cook components, not full meals. The same roasted chicken becomes a wrap on Monday, a salad on Tuesday, a grain bowl on Wednesday and a stir-fry on Thursday.
Use the oven for two trays at once — proteins on one, veg on the other.
Store food so it actually keeps
- Cool food fully before lidding to avoid sogginess
- Store sauces separately from greens
- Portion proteins individually for easy grab-and-go
- Freeze anything you won't eat by day 4
Assemble meals in 5 minutes
Mix and match: 1 grain + 1 protein + 1–2 veg + healthy fat + sauce. Done.
This formula gives you 30+ different meals from the same Sunday prep.
Stay under budget
- Buy proteins on sale and freeze the extras
- Use frozen vegetables — same nutrients, half the price
- Lentils and eggs are the cheapest protein per gram
- Plan around what's in season
Common meal-prep mistakes
- Cooking 7 identical lunches (boredom by Wednesday)
- Trying complicated recipes the first week
- Storing greens with hot food (they wilt)
- Skipping the sauce — it's what makes everything work
Key takeaways
- Prep components, not full meals.
- 90 minutes on Sunday = 5–6 days of healthy meals.
- Use the formula: grain + protein + 2 veg + fat + sauce.
- Cool food before sealing — and store sauces separately.
- Start simple. Boring beats burnout.
