Ingredients

Fajita seasoning

Fajitas

  • 1 1/2 lbs. boneless skinless chicken breasts
  • 4 Tbsp fajita seasoning divided
  • juice of 1 lime
  • 3 1/2 Tbsp vegetable oil divided
  • 2 Tbsp minced fresh cilantro
  • 1 medium red bell pepper seeded and sliced into thin strips
  • 1 poblano pepper seeded and sliced into thin strips
  • 1 large yellow onion sliced into thin strips
  • juice of half a lime to squeeze over the skillet to finish

Instructions

Prepare

Marinate chicken

  • Add chicken breasts, 3 Tbsp of fajita seasoning, juice of 1 lime, 1 1/2 Tbsp of the vegetable oil, and minced cilantro to a large resealable plastic bag.  Seal and massage mixture into the chicken.  Alternately, add everything to a bowl and massage into the chicken, then cover tightly with plastic wrap. Marinate for at least 20 minutes, or up to a couple hours.

Cook chicken

  • Heat a large cast iron skillet (or other heavy bottomed skillet) over MED HIGH heat with 2 Tbsp of vegetable oil.  When oil is hot, add chicken and cook 6-8 minutes per side, until deep golden brown on both sides and cooked through.  Transfer chicken to plate and let rest for about 5-10 minutes.

Cook vegetables

  • While chicken is resting, add sliced bell pepper, sliced poblano, and sliced onion to the same skillet.  Sprinkle with remaining 1 Tbsp fajita seasoning, and drizzle with a little more vegetable oil. Cook, stirring occasionally, for about 4-5 minutes, or until tender and charred at the edges.

Slice chicken

  • While peppers and onions are cooking, slice chicken breast into thin strips.

Put it all together

  • Slide peppers and onions over to one side of the skillet, then add the sliced chicken to the other side of the skillet. 
  • Squeeze half a lime over the skillet and stir to combine everything.

Serve

  • Serve with lime wedges and warmed tortillas. Top with your favorite toppings, like guacamole, sour cream, minced fresh cilantro, and more!
