Ingredients

Scale
  • 1.5 lbs flank steak or skirt steak, sliced against the grain into thin strips
  • 1 large red bell pepper, sliced
  • 1 large green bell pepper, sliced
  • 1 large yellow onion, sliced
  • 2 tablespoons olive oil, divided
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1 teaspoon chili powder
  • 1 teaspoon ground cumin
  • 1/2 teaspoon smoked paprika
  • 1/4 teaspoon cayenne pepper (optional)
  • 2 cloves garlic, minced
  • 1/4 cup fresh lime juice
  • 10 small flour tortillas

Instructions

  1. Combine the sliced steak with 1 tablespoon of olive oil, salt, pepper, chili powder, cumin, smoked paprika, cayenne pepper (if using), minced garlic, and lime juice in a bowl. Mix well to coat. Marinate for at least 15 minutes, or up to 4 hours in the refrigerator.
  2. Heat 1 tablespoon of olive oil in a large skillet over medium-high heat until shimmering.
  3. Add the sliced onions and bell peppers to the hot skillet. Cook for 5 to 7 minutes, stirring occasionally, until the vegetables are tender-crisp. Remove the vegetables from the skillet and set them aside.
  4. Add the marinated steak strips to the same hot skillet in a single layer if possible. Cook for 2 to 4 minutes per side until browned and cooked to your desired doneness. Do not overcrowd the pan; cook in batches if necessary to maintain high heat.
  5. Return the cooked vegetables to the skillet with the steak. Toss everything together for 1 minute to heat through.
  6. Warm the flour tortillas according to package directions (in a dry pan or microwave).
  7. Serve the sizzling steak and vegetable mixture immediately with the warm tortillas and your favorite toppings.

Notes

  • For extra flavor, add 1 teaspoon of brown sugar to the marinade.
  • If you prefer a less intense sear, cook the steak and vegetables separately and combine only when serving.
  • Serve with sour cream, salsa, guacamole, or shredded cheese.
