Ingredients

Scale
  • 1 pound boneless, skinless chicken breasts or thighs, sliced into thin strips
  • 1 red bell pepper, thinly sliced
  • 1 yellow bell pepper, thinly sliced
  • 1 green bell pepper, thinly sliced
  • 1 large yellow or white onion, thinly sliced
  • 2 tablespoons olive oil (plus extra for cooking)
  • 2 cloves garlic, minced
  • 1 teaspoon chili powder
  • 1 teaspoon smoked paprika
  • 1/2 teaspoon ground cumin
  • 1/4 teaspoon cayenne pepper (optional)
  • 1/2 teaspoon dried oregano
  • Juice of 1 lime (about 2 tablespoons)
  • Salt and freshly ground black pepper, to taste
  • Flour or corn tortillas for serving
  • Optional toppings: sour cream, shredded cheese, fresh cilantro, sliced avocado, or salsa

Instructions

  1. Prepare the marinade by whisking together olive oil, minced garlic, chili powder, smoked paprika, ground cumin, cayenne pepper (if using), dried oregano, lime juice, salt, and pepper in a mixing bowl.
  2. Add the sliced chicken to the marinade, toss to coat evenly, cover, and refrigerate for at least 20 minutes or up to 1 hour.
  3. While the chicken marinates, thinly slice the bell peppers and onion into uniform strips about 1/4-inch thick.
  4. Heat a large skillet over medium-high heat and add a drizzle of olive oil. Cook the marinated chicken in a single layer for 3-4 minutes per side until browned and cooked through. Remove chicken and set aside.
  5. In the same skillet, add more oil if needed and sauté the sliced peppers and onions over medium heat for 5-7 minutes until softened with slight charred edges. Season lightly with salt and pepper.
  6. Return the cooked chicken to the skillet with the peppers and onions, stir to combine, and cook for another 1-2 minutes to meld flavors. Adjust seasoning as needed.
  7. Warm the tortillas in a dry skillet or microwave wrapped in a damp paper towel for about 30 seconds until pliable.
  8. Serve the chicken and veggie mixture on warm tortillas with optional toppings like sour cream, shredded cheese, cilantro, or avocado slices.

Notes

Marinate chicken for at least 20 minutes for best flavor; cooking in batches prevents soggy chicken; cook peppers and onions over medium heat for caramelization without burning; warm tortillas before serving to keep them soft; add a splash of water or chicken broth if pan dries out during cooking.
