- Meal prep is the #1 strategy for successful low FODMAP adherence. When you're hungry and have no prepared food, you'll grab something that triggers symptoms. Every time.
- This guide gives you 5 lunches and 5 dinners in approximately 2 hours of Sunday cooking. Total cost: approximately $40-60.
- The core method: cook 3 proteins, 2 starches, and 3 vegetables. Mix and match throughout the week for variety.

The 2-Hour Prep Plan
Step 1: Start the Rice (5 minutes active, 20 passive)
Cook 4 cups rice in a rice cooker or pot. This makes ~8 cups cooked rice — enough for 8 servings throughout the week. Set it and forget it while you do everything else.
Step 2: Season and Roast the Chicken (10 minutes active, 40 passive)
Pat chicken thighs dry. Drizzle with garlic-infused oil. Season with smoked paprika, salt, pepper. Arrange on a sheet pan. Roast at 425°F for 35-40 minutes until skin is crispy and internal temp is 165°F. The rendered chicken fat = liquid gold for flavoring other dishes.
Step 3: While Chicken Roasts — Make Turkey Bolognese (20 minutes)
Brown ground turkey in a large skillet with garlic-infused oil. Add 2 cans crushed tomatoes, 1 tsp dried oregano, 1 tsp Italian seasoning, salt, pepper. Simmer 15 minutes while you prep vegetables. This yields 4 servings.
Step 4: Prep and Roast Vegetables (10 minutes active, 25 passive)
On a second sheet pan (goes in after chicken comes out): sliced zucchini, diced bell peppers, and halved green beans. Toss with olive oil, salt, and Italian seasoning. Roast at 400°F for 25 minutes. Do the carrots separately — slice into sticks, toss with oil, cumin, and salt. Roast alongside.
Step 5: Cook the Salmon (10 minutes)
Season salmon with garlic-infused oil, lemon juice, dill (or dried herbs), salt, pepper. Pan-sear in a hot skillet: 4 min skin-down, flip, 3 min flesh-down. Done. Or bake at 400°F for 12 minutes.
Step 6: Cook the GF Pasta (10 minutes)
Boil GF pasta per package directions. Drain, toss with a drizzle of olive oil to prevent sticking. Cool.
Step 7: Portion into Containers (15 minutes)
Use 10 containers (5 lunches + 5 dinners):

Meal Prep Tips
- Invest in glass containers: They reheat better, don't stain, and last years. A 10-pack costs $20-30 and pays for itself in saved takeout within a week.
- Label everything: Use masking tape + marker with the contents and date.
- Refrigerate for 4 days, freeze for longer: Meals for Monday-Thursday can be refrigerated. Friday meals or extras should be frozen immediately.
- Add variety at serving time: Different sauces (soy sauce, lemon juice, hot sauce), different toppings (sesame seeds, herbs, cheese), and different temperatures (cold salmon salad vs. warm salmon rice bowl) make the same proteins feel like different meals.
- Double and freeze: If you're already prepping, make double and freeze half. Next week's prep takes zero time.
🛒 Meal Prep Partners
- Digestive Enzymes — Keep a bottle at your desk and one in your meal prep bag. Take with every prepped meal for thorough digestion. Meal prep meals are eaten quickly during busy workdays — enzymes ensure they're properly broken down even when you're eating fast.
- Whey Protein — When your prepped meal feels light on protein, a quick shake alongside boosts total intake. Also serves as a backup meal when your containers run out: one scoop + water or milk = 25g protein in 30 seconds.
