  • 3 tbsp avocado oil
  • 1 red bell pepper
  • 1 orange (or yellow) bell pepper
  • 1 green bell pepper
  • 1 medium onion
  • 1-1.5 lbs chicken breasts
  • 1.5 tsp cumin
  • 2 tsp chili powder
  • 1 tsp garlic powder
  • 1 tsp paprika
  • 1/2 tsp oregano
  • 1 tsp sea salt
  • 1/2 tsp black pepper
  • 1/2 tsp red pepper flakes


  • Preheat your oven to 400 degrees. Slice the peppers, onion, and chicken into thin strips (about 1/4-1/2 inch wide). Make sure the chicken pieces are of even thickness to prevent uneven cooking.
  • Put these pieces into a large bowl and add the avocado oil and spices. Mix together and spread out evenly on a parchment lined rimmed baking sheet.
  • Bake for 25-30 mins until cooked through and beginning to brown. Serve in tortillas, on top of a salad, or in a rice bowl with your favorite toppings. Enjoy!
