Ingredients

Scale
  • 1 pound boneless, skinless chicken breasts, sliced into thin strips
  • 2 medium bell peppers (red, yellow, green), sliced into thin strips
  • 1 large yellow onion, thinly sliced
  • 2 tablespoons olive oil or avocado oil
  • 2 cloves garlic, minced
  • 1 teaspoon ground cumin
  • 1 teaspoon smoked paprika
  • 1 teaspoon chili powder
  • 1/2 teaspoon dried oregano
  • 1/2 teaspoon kosher salt
  • 1/4 teaspoon freshly ground black pepper
  • Juice of 1 lime
  • Fresh cilantro, chopped (optional, for garnish)
  • 8 small flour or corn tortillas

Instructions

  1. Slice 1 pound of boneless, skinless chicken breasts into thin strips about 1/4 inch thick and place in a mixing bowl.
  2. In a small bowl, combine 1 teaspoon ground cumin, 1 teaspoon smoked paprika, 1 teaspoon chili powder, 1/2 teaspoon dried oregano, 1/2 teaspoon kosher salt, and 1/4 teaspoon freshly ground black pepper. Stir well.
  3. Add the spice blend and minced garlic (2 cloves) to the chicken. Drizzle 1 tablespoon olive oil over it and toss until evenly coated. Marinate for 10 minutes if possible.
  4. Heat 1 tablespoon olive oil in a large skillet over medium-high heat. Add sliced bell peppers and onion. Cook, stirring occasionally, for 5–7 minutes until veggies are tender-crisp and caramelized. Remove and set aside.
  5. In the same pan, add chicken strips in a single layer. Sear undisturbed for 2–3 minutes until golden crust forms, then stir and cook another 3–4 minutes until cooked through (internal temperature 165°F).
  6. Return peppers and onions to the pan with chicken. Stir and cook for 1–2 minutes to combine flavors and heat through.
  7. Remove from heat and squeeze fresh lime juice over the mixture. Stir gently.
  8. Warm tortillas by placing them in a dry skillet for 15–20 seconds per side or wrap in foil and heat in a 300°F oven for 10 minutes.
  9. Serve chicken and veggie mixture on warm tortillas. Garnish with chopped cilantro if desired.

Notes

Slice chicken against the grain for tenderness. Do not stir peppers and onions too often to allow caramelization. Marinate chicken for at least 10 minutes for deeper flavor. Use medium-high heat for perfect sear. Warm tortillas last to keep them soft. For gluten-free, use corn tortillas. Chicken thighs can be substituted for juicier meat. Avoid microwaving tortillas directly to prevent dryness.
