  • 2 tablespoons olive oil
  • 2 tablespoons lime juice
  • 2 cloves garlic, finely minced
  • 2 teaspoons chili powder
  • 1 teaspoon cumin
  • 1 teaspoon salt
  • ½ teaspoon black pepper


  • 2 pounds boneless skinless chicken breasts, cut into thin strips
  • 2 tablespoons olive oil, divided
  • 2 medium red bell peppers, sliced into thin strips
  • 2 medium onions, sliced into thin strips
  • salt and pepper, to taste
  • 16 taco-sized (6 to 8-inch) flour tortillas, warmed
  • toppings of your choice


  • In a large bowl, whisk together the marinade ingredients until well combined.
  • Add the thinly sliced chicken to the marinade and stir to coat the chicken evenly with the marinade; set aside.
  • In a large skillet (I use a 12-inch cast iron skillet), heat 1 tablespoon of olive oil over medium-high heat. Add the peppers and onions, season with salt and pepper, and cook, stirring frequently, until they are crisp-tender and just start to get a little bit of brown color on them.
  • Remove the peppers and onions from the skillet to a bowl or plate; set aside.
  • In the same skillet over medium-high heat, add the remaining tablespoon of olive oil. Add the chicken and the marinade and cook, stirring frequently, until the chicken is cooked through.
  • Add the peppers and onions back to the skillet with the chicken and mix to combine. Cook for a minute or two just to make sure everything is warmed through.
  • Serve with warm tortillas and your favorite toppings.

Recipe Notes

  • Suggested toppings: sour cream, cheese, salsa or pico de gallo, guacamole, fresh cilantro, lime juice.
  • Calorie estimate is for two fajitas per serving (chicken mixture and tortillas) and does not include any toppings.
