Ingredients
Scale
Steak and Marinade
- 2 pounds sirloin steak, cut into thin strips
- 1 tbsp lime juice
- ½ teaspoon chili powder
- ⅛ teaspoon cayenne pepper
- 2 minced garlic cloves
- 1 tbsp olive oil (for marinade)
Vegetables
- 1 red bell pepper, thinly sliced
- 1 yellow bell pepper, thinly sliced
- 1 green bell pepper, thinly sliced
- 1 large yellow onion, thinly sliced
Additional Ingredients
- 1 tbsp olive oil (for cooking)
- 2 cups Mexican blend cheese, grated
- 6 to 8 tortillas
Instructions
- Marinate the Steak: In a zip-lock bag, combine the thinly sliced sirloin steak with chili powder, cayenne pepper, lime juice, minced garlic, and 1 tablespoon of olive oil. Seal the bag and shake well to ensure the steak pieces are evenly coated with the marinade.
- Add Vegetables to Marinade: Open the bag and add the thinly sliced red, yellow, and green bell peppers along with the yellow onion. Seal the bag again and shake to coat the vegetables evenly with the marinade and steak juices.
- Heat the Skillet: Place a large skillet over medium-high heat and add 1 tablespoon of olive oil. Allow the oil to heat until shimmering but not smoking.
- Cook Steak and Vegetables: Pour the contents of the bag, including steak and coated vegetables, into the heated skillet. Stir occasionally and cook until the vegetables become just tender and the steak is fully cooked through, typically about 7-10 minutes depending on thickness.
- Warm the Tortillas and Serve: Warm the tortillas separately by heating them in a dry skillet or microwave. Serve the cooked steak and vegetable mixture wrapped in the tortillas, topped with a generous sprinkle of grated Mexican blend cheese and any optional toppings of your choice such as sour cream, guacamole, or salsa.
Notes
- You can adjust the cayenne pepper to control the heat level to your preference.
- Using a cast-iron skillet can enhance the sear on the steak for extra flavor.
- Allow the steak to marinate for at least 30 minutes for deeper flavor, if time permits.
- For a low-carb version, replace tortillas with lettuce wraps.
- Serve with fresh lime wedges and chopped cilantro for added brightness.
