Ingredients

For the steak and marinade:

1 lb (450 g) sirloin steak, thinly sliced
3 tablespoons olive oil
2 tablespoons lime juice (freshly squeezed)
2 cloves garlic, minced
1 teaspoon smoked paprika
1 teaspoon ground cumin
½ teaspoon chili powder
½ teaspoon salt
¼ teaspoon black pepper

For the vegetables:

1 red bell pepper, thinly sliced
1 yellow bell pepper, thinly sliced
1 green bell pepper, thinly sliced
1 large onion, thinly sliced
1 tablespoon olive oil
Salt and pepper, to taste

For serving:

6 small flour or corn tortillas
Optional toppings: sour cream, guacamole, salsa, shredded cheese, fresh cilantro, lime wedges

Step-by-Step Method

1. Prepare the Marinade

In a medium bowl, combine olive oil, lime juice, minced garlic, smoked paprika, cumin, chili powder, salt, and black pepper. Whisk until the ingredients are fully blended. This marinade will infuse your steak with a deep, smoky, and slightly tangy flavor.

2. Marinate the Sirloin

Place the thinly sliced sirloin steak into a shallow dish or a resealable plastic bag. Pour the marinade over the steak, ensuring every piece is coated. Cover the dish or seal the bag and refrigerate for at least 30 minutes — ideally 2 hours. Marinating not only enhances flavor but also helps tenderize the meat.
