Ingredients

  • 2 lb flank steak sliced
  • 3 bell peppers seeded and sliced
  • 1 large onion sliced
  • 2 tbsp olive oil divided
  • 2 tbsp taco seasoning or fajita seasoning
  • 1/2 bunch cilantro chopped

Instructions

  • Heat 1 tablespoon of oil in a large skillet over medium-high heat.
  • Add the steak in a single layer (cook in batches if needed to avoid overcrowding the pan), and sprinkle with 1 tablespoon of seasoning.
  • Cook for around 1-2 minutes per side. Set aside.
  • To the same skillet, add the remaining oil and stir fry the veggies for 3-4 minutes.
  • Stir in the remaining taco seasoning.
  • Remove from heat and return the steak; stir to combine.
  • Serve in corn tortillas if desired with toppings of choice.

Notes

  • Cut the flank steak against the grain to make the steak less tough. This shortens the beef fibers and makes chewing much easier.
  • Cook flank steak to medium-rare for the most tender texture. A well-done steak will be chewy and harder to break down.
  • Use any color of bell pepper you prefer! If you're not a fan of green bell peppers, stick to red, yellow, and orange.
  • Store any leftovers from this steak fajita recipe in the fridge for up to 4 days.
  • Reheat them in the microwave or in a pan on the stove with a bit of oil.
  • Serve with guacamole, salsa, chopped fresh cilantro, and a squeeze of fresh lime!
