Place 3 lbs flank steak in a crock pot. Rub 1 tablespoon olive oil over the steak.
In a small bowl, mix together 2 teaspoons minced garlic, 1 tablespoon chili powder, 1 teaspoon paprika, 1 teaspoon salt, 1 teaspoon pepper, and 1 teaspoon cumin. Rub this mixture evenly over the steak.
Top the steak with the juice from 1 lime, ½ cup chopped cilantro, and ½ white onion (chopped).
Pour 1 cup beef broth around the steak in the crock pot.
Cover and cook on low for 6–8 hours or on high for 3–4 hours until the steak shreds easily.
After the cook time, shred the beef and squeeze the juice from the remaining lime over the shredded meat.
Melt ¼ cup butter in a large skillet or on a griddle.
Fry 24 mini corn tortillas in the melted butter for about 1 minute or until the tortillas are soft.
Allow the tortillas to cool slightly.
Fill the tortillas with the shredded beef and your favorite taco toppings. Use 2 mini corn tortillas per taco and serve.

Notes
Refrigerate the leftovers in an air tight container for up to 5 days. Skirt steak or sirloin instead of the flank steak can be used in this recipe.
