Ingredients

For the Fajitas:

  • 1 1/2 pounds skirt steak may also use flank steak, sliced into 1/2-1 inch strips
  • 1/2 cup lime juice
  • 1/2 cup coconut aminos
  • 1/4 cup avocado oil
  • 1 tablespoon minced garlic
  • 1 tablespoon fresh grated ginger

For the Vegetables:

  • 1 teaspoon avocado oil
  • 1 red bell pepper cut into 1/2 inch strips
  • 1 green bell pepper cut into 1/2 inch strips
  • 1 onion thinly sliced

For Serving (optional):

  • Cheese
  • Sour Cream
  • Guacamole
  • Fresh Chopped Cilantro

Instructions

  • Whisk together the ingredients for the marinade. Add the sliced steak to the marinade and let sit, covered, for at least 4 hours up to 1 day.
  • Remove the steak strips from the marinade and pat dry.
  • Bring a cast iron pan or griddle to medium-high heat. Once hot, add the fajitas and sear for 3-4 minutes per side, until charred, then remove from pan.
  • Set the steak aside to rest, then add the bell pepper and onion to the pan over medium-high heat. Cook for 4-5 minutes until charred, stirring occasionally.
  • Plate the fajitas with the peppers and onion, then serve alongside tortillas, cheese, sour cream, guacamole, cilantro, and pickled jalapeños, if desired.
