  3. Seed and cut the bell peppers into thin strips. Cut the onion into thin strips after removing the ends and outer skin.
  4. In a medium bowl, combine the chicken pieces, cut peppers, onions, and minced garlic. Toss everything with olive oil.
  5. Sprinkle all the seasonings (except cilantro) over the mixture and stir until well combined.
Cooking

  2. Bake for 20 minutes or until the chicken is no longer pink inside, and the veggies are tender. Remove from the oven and sprinkle with chopped cilantro.

Notes

These fajitas are best served in butter lettuce leaves for a fresh crunch! You can also use gluten-free tortillas for a delightful wrap or enjoy everything in a cozy burrito bowl. Store any leftovers in an airtight container in the fridge for up to three days. Reheat gently in the microwave or on the stovetop to bring back that delicious taste. Adjust the spices based on your heat preference; add cayenne pepper for extra spice. Consider adding zucchini or mushrooms for extra greens.
