03 - Add chicken strips, sliced bell peppers, and red onion to the bowl. Toss thoroughly until all pieces are evenly coated with the marinade.
04 - Spread the marinated chicken and vegetables in a single layer on the prepared baking sheet.
05 - Roast in the preheated oven for 22 to 25 minutes, stirring halfway through, until chicken is fully cooked and vegetables are tender with slight charring.
06 - Remove from oven and serve immediately with warmed tortillas and preferred toppings.

# Expert Suggestions:

01 -
  • Everything happens on one pan so cleanup is literally just tossing some foil
  • The marinade creates these gorgeous caramelized edges on the chicken and peppers that taste like restaurant quality
02 -
  • Do not overcrowd the pan or your vegetables will steam instead of getting those delicious charred spots
  • Stirring halfway through is the secret to even cooking and preventing the chicken from drying out while the vegetables catch up
03 -
  • Slice your vegetables and chicken to roughly the same thickness so everything finishes cooking at the same time
  • Let the marinated mixture sit for 15 minutes before roasting if you have time for deeper flavor penetration
