Ingredients

  • 3/4 pound leftover flank steak cut against the grain into strips
  • 2 tablespoons oil divided
  • 1 red bell pepper cut into strips
  • 1 green bell pepper cut into strips
  • 1 medium onion sliced
  • 1 tablespoon lime juice 1/2 lime
  • 2 cloves of garlic minced
  • 1/4 teaspoon cumin
  • 1/8 teaspoon crushed red pepper
  • salt and pepper to taste
  • 8 tortilla shells corn or flour
  • 1/2 cup queso fresco or shredded Mexican cheese

Optional Toppings

  • 4 stems fresh cilantro chopped
  • Sour cream

Instructions
 

  • In a medium bowl, combine the peppers, onion, 1 tablespoon oil, minced garlic, cumin, lime juice, and red pepper. Toss to coat.
  • Preheat a cast iron skillet over medium heat with remaining 1 tablespoon of oil.
  • Add the pepper and onion mixture to the pan and saute until the onions are opaque and the peppers have softened, about 5 to 10 minutes.
  • Push the peppers and onions to one side of the skillet and add the sliced leftover steak to the other side to warm it up.
  • Warm tortillas in the oven or air fryer wrapped in foil, on a skillet sprayed with oil, or in the microwave covered with a damp paper towel.
  • Add the flank steak, peppers, onions, and queso fresco into each tortilla and serve!

Notes

Use a tender slice of steak, like a flank or skirt steak for a flavorful and tender fajita.
