Ingredients

  • 2 lb sirloin steak sliced into thin strips
  • 1 red bell pepper thinly sliced
  • 1 yellow bell pepper thinly sliced

  • 1 tbsp fresh lime juice
  • ½ tsp chili powder
  • 1 tsp ground cumin

Instructions

  • In a large zip-top bag, combine the sliced steak, lime juice, chili powder, cumin, cayenne pepper, minced garlic, and 2 tablespoons of olive oil. Seal the bag and gently shake to evenly coat the steak.
