Ingredients

  • 1 lb beef strips
  • ½ tablespoon ground cumin
  • ½ teaspoon ground oregano
  • ½ teaspoon chili powder
  • ½ teaspoon ground cayenne (optional)
  • 1 teaspoon salt
  • ½ teaspoon ground pepper
  • 2 tablespoon oil
  • ½ onion sliced
  • 1 garlic clove finely minced
  • 1 green bell pepper sliced
  • 1 red bell pepper sliced
  • 1 yellow bell pepper sliced
  • 2 limes (juice)

Instructions

  • Rinse the beef strips and pat dry.
  • Sprinkle with cumin, oregano, cayenne (if using), chili powder, salt, and pepper.
  • In a large skillet, heat 2 tablespoons of olive oil.
  • Add beef and cook for 4 minutes.
  • Stir occasionally. You want a good sear on the beef.
  • Add the peppers, onion, and garlic.
  • Cook for an additional 4-5 minutes, or until the peppers are soft.
  • Turn heat off. Squeeze lime juice all over the beef and peppers.
  • Stir to combine.
  • Serve with tortillas, salsa, and enjoy!

Notes

Rinse the beef strips, and pat dry well with a paper towel. This will ensure a good sear on the beef. 
Use all the bell peppers, a combination of two, or choose one and use more of it. It's up to you and personal preference.
