  • Preheat your oven to 400°F (200°C).
  • In a large mixing bowl, combine the sliced chicken, bell peppers, and red onion.
  • Drizzle olive oil over the mixture and sprinkle fajita seasoning, salt, and pepper. Toss until well-coated.
  • Spread the seasoned chicken and vegetable mixture evenly on a large sheet pan.
  • Roast in the preheated oven for about 20 minutes, or until the chicken is cooked through and the vegetables are tender.

  • Once the chicken and veggies are ready, remove them from the oven.
  • Using tongs, place a generous amount of the chicken and vegetable mixture on one half of each tortilla.
