  • 1 tablespoon sugar
  • ¾ teaspoon salt
  • 1 tablespoon chili powder
  • 1.5 teaspoon cumin
  • 1.5 teaspoon paprika
  • ½ teaspoon garlic powder
  • ½ teaspoon onion powder
  • ⅛-1/4 teaspoon cayenne optional


  • 2 chicken breasts (roughly 1 lb; sliced into strips)
  • 2 bell peppers (sliced into strips)
  • 1 red onion (sliced into strips)
  • 1 zucchini (optional; sliced into strips)
  • 1 cup mushrooms (optional; quartered)
  • juice from 1 lime

To Serve

  • 8 6 inch tortillas (or tortilla boats)
  • avocado

  • Pre-heat oven to 425°F.

  • Toss the chicken and veggies in a large bowl with the olive oil and lime juice.
  • Add the rub and stir to coat.
  • Arrange chicken and veggies on 1-2 large sheet pans.
  • Roast for 10 minutes, flip and roast for another 5-10 minutes, or until chicken is cooked through.
  • Serve in tortillas with your favorite fajita toppings (avocado, cilantro, greek yogurt, sour cream, salsa, pico de gallo, jalapeno slices are a few ideas).

To assemble ahead

  • Complete steps 2-4, then transfer to a large storage container or bag.
  • Store in the fridge (see *note) for up to 3 days (check the expiry date on your chicken to be sure it is safe to keep that long).
  • Dump onto sheet pans and cook as directed above.

To cook ahead

  • After cooking and cooling completely, divide the fajita filling between four 2 cup meal prep containers.
  • Store in the fridge for up to 4 days.
  • Reheat in the microwave until steaming hot, then spoon into tortillas or tortilla boats.
