- Remove seeds and stems from all peppers. Slice each pepper into strips of equal size. Slice red onion into thin strips.

- Sprinkle remaining spice mixture over all chicken breasts covering both sides evenly.
- Toss all vegetables onto lined baking sheet evenly spreading out. Top chicken pieces over the peppers. Drizzle 1 Tbsp olive oil over top of chicken pieces.
- Cook for 30 minutes, tossing chicken at halfway point.
- When chicken and peppers have cooled, slice each chicken breast into even pieces. Start distributing cauliflower among all five meal prep containers. Add peppers and top each meal prep container with one chicken breast. You should have five meals for the week, enjoy!
