Essential Equipment
Must-Have Items
- Quality containers – Glass or BPA-free plastic, various sizes (2-cup and 4-cup)

|---|---|---|---|
| Sheet Pan Roast | Thighs/Breasts | 25-35 min @ 425°F (220°C) | ~6 servings |

Storage Best Practices
- Cool before storing: Let food cool to room temp (max 2 hours) before refrigerating
- Portion immediately: Divide into serving sizes while still warm for easier handling
- Label everything: Include contents, date cooked, and "use by" date
- Use the 3-2-1 method: Prep 3 days in fridge, freeze rest for days 4-7
- Store sauces separately: Keeps proteins from getting soggy

Tips for Success
Keep It Simple
Start with 2-3 proteins per week. Master the basics before adding complexity.
Flavor Variety Through Sauces
Cook proteins plain, then vary flavors with different sauces. Same chicken, different meals.
Strategic Freezing
Freeze half immediately. Prevents waste and ensures fresh-tasting meals all week.
Prep When You Shop
Right after grocery shopping is the best time to prep while ingredients are freshest.
Common Mistakes to Avoid
❌ Overcomplicating the First Week
Don't try to prep 7 different proteins. Start with 2-3 and build from there.
❌ Not Portioning Properly
Bulk containers mean guessing portions daily. Pre-portion everything for accuracy.
❌ Ignoring Food Safety
Leaving food out too long or keeping it past safe dates. When in doubt, throw it out.
❌ Mixing Wet and Dry Components
Store dressings, sauces, and grains separately to prevent soggy meals.
❌ No Backup Plan
Keep emergency protein on hand (canned fish, protein powder, eggs) for when plans change.
