In a large skillet, heat the olive oil over medium heat. Add the diced onion and cook for 3-4 minutes, or until softened.

1. Add the minced garlic to the skillet and cook for another 1 minute, until fragrant.
2. Stir in the drained and rinsed beans, chili powder, cumin, paprika, salt, and pepper. Cook for 5-7 minutes, mashing the beans slightly with a spoon or potato masher for texture. Leave some beans whole for added bite.
3. While the beans are cooking, warm the taco shells in the oven or microwave according to package instructions.
4. Once the beans are heated through and well-seasoned, remove from heat and set aside.
5. To assemble the tacos, spoon the seasoned beans into each taco shell. Top with your favorite toppings like shredded lettuce, diced tomatoes, avocado slices, salsa, sour cream, cheese, and a sprinkle of fresh cilantro.
6. Serve with lime wedges for an added burst of freshness.
