Ingredients

Scale

2 pounds beef flank steak, thinly sliced against the grain
3 bell peppers (1 red, 1 green, 1 yellow), thinly sliced
1 large yellow onion, thinly sliced
3 cloves garlic, minced
1/4 cup lime juice (about 2 limes)
1/4 cup beef broth
2 teaspoons chili powder
1 teaspoon ground cumin
1 teaspoon smoked paprika
1/2 teaspoon dried oregano
1/2 teaspoon salt
1/4 teaspoon black pepper
2 tablespoons olive oil
8 small flour tortillas

Instructions

In a small bowl, combine chili powder, ground cumin, smoked paprika, dried oregano, salt, and black pepper. Mix well.
Place the thinly sliced beef flank steak in a large bowl. Add the spice mixture and toss to coat the beef evenly.
Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Add the beef strips and sear for 2-3 minutes until browned but not cooked through. Remove from heat.
Add the sliced bell peppers, sliced onion, and minced garlic to the slow cooker.
Place the seared beef strips on top of the vegetables in the slow cooker.
Pour the lime juice and beef broth over the beef and vegetables.
Drizzle the remaining 1 tablespoon of olive oil over the mixture.
Cover and cook on low for 6 hours, or until the beef is tender and the vegetables are soft.
Once cooked, stir the beef and vegetables to combine and distribute the juices.
Warm the flour tortillas according to package instructions.
Serve the beef and vegetable mixture on the warm tortillas. Optionally, garnish with fresh cilantro, sour cream, or shredded cheese if desired.
