Ingredients

Chicken Marinade

  • ½ cup avocado oil divided
  • ¼ cup soy sauce
  • 2 tablespoons honey
  • 3 chipotle chili peppers diced
  • 2 teaspoons chili powder
  • 2 teaspoons salt
  • 2 teaspoons garlic powder
  • 1 teaspoon ground cumin
  • 1 teaspoon smoked paprika
  • 2 ½ pounds boneless skinless chicken breast cut into thin strips (chicken thighs may also be used)

Fajitas

  • 2 tablespoons avocado oil divided; more as needed
  • 2 onions yellow, red or a combination
  • 2 bell peppers any color
  • 12 tortillas
  • For serving: shredded cheese avocados, guacamole, tomatoes, sour cream, cilantro, salsa, pico de gallo, hot sauce

Instructions

  • In a jar or blender, combine all but a tablespoon of the oil, soy sauce, honey, chipotle peppers, chili powder, salt, garlic powder, cumin, and smoked paprika. Shake or blend until combined.
  • Place the sliced chicken in a shallow dish or bowl, then pour the marinade over it. Refrigerate for at least 4 hours, or up to 24 hours.
  • Drain the marinade and pat the chicken dry.
  • Heat your cast iron skillet to medium-high heat.
  • Add the remaining tablespoon of the oil.
  • Add the peppers and the onions and cook for 6 to 9 minutes, until cooked through.
  • Remove from the heat. Add the remaining oil to the skillet and add the chicken, cooking in batches if necessary. Cook for 7 to 10 minutes, until golden and cooked through. I like to return all of the chicken to the pan at the end for about 2 minutes so that it is evenly warm.
  • Heat the tortillas in the microwave under a damp cloth for 30 seconds.
  • Serve the chicken and vegetables on the tortillas with desired fixings and a lime wedge on the side.

Notes

Storage
Store leftovers in an airtight container in the refrigerator for up to three days.
