Ingredients
  

Main Ingredients
  • 2.5 lbs flank steak or skirt steak
  • 3 large bell peppers various colors
  • 2 large onions
  • 10-20 flour tortillas
For the Marinade
  • 1/4 cup olive oil
  • 1/4 cup lime juice
  • 2 tbsp chili powder
  • 1 tbsp cumin
  • 1 tbsp paprika
  • 1 tsp garlic powder
  • 1 tsp onion powder
  • 1/2 tsp cayenne pepper optional
  • Salt to taste
  • Black pepper to taste
Optional Toppings
  • sour cream, salsa, guacamole, shredded cheese, chopped cilantro, extra lime wedges

Equipment

  • Large bowl
  • Cutting board
  • Large skillet or cast-iron pan

Method
 

Preparation
  1. Slice the beef flank or skirt steak thinly against the grain; then, in a bowl, mix olive oil, lime juice, chili powder, cumin, paprika, garlic powder, onion powder, cayenne pepper, salt, and black pepper for the marinade.
  2. Add the beef strips to the marinade, tossing to coat evenly, and let it marinate for at least 30 minutes, or up to 4 hours, in the refrigerator.
Cooking
  1. Slice the bell peppers and onions into thin strips while the beef marinates.
  2. Heat a large skillet or cast-iron pan over medium-high heat with a little oil, then cook the marinated beef in batches until browned and cooked through, approximately 3-5 minutes per batch, and set aside.
  3. In the same pan, add more oil if necessary and cook the sliced bell peppers and onions until they are softened and slightly charred, about 5-7 minutes.
  4. Return the cooked beef to the pan with the vegetables, tossing to combine and heating through for about a minute.
  5. Warm the tortillas according to their package directions using a microwave, oven, or skillet.
Serving
  1. Serve the beef and vegetable mixture immediately with warm tortillas and your preferred toppings like sour cream, salsa, or guacamole.

Notes

For best flavor, marinate the beef for at least 2 hours. Adjust the amount of cayenne pepper to your spice preference. Don't overcrowd the pan when cooking the beef to ensure it browns properly instead of steaming.
