Overview
Why it works
The single best meal-prep recipe in the library. Slice, season, roast - four servings of fajita filling that pivot into burritos, bowls, salads or lettuce wraps all week.
- Chicken thigh stays juicy after reheating - far more forgiving than breast for meal prep.
- High-heat roasting caramelizes the peppers and onions for restaurant-grade flavor.
- Built-in macro flexibility - you control the carb (rice, tortilla, lettuce, none).

Pro Tips
Coach-level details
- Use two sheet pans if it looks crowded - overcrowding steams instead of roasts.
- Save pan juices and pour over your reheated portions during the week.
- Try the broiler for the last 2 minutes for a stronger char.
