Making Crispy Black Bean Tacos with Cilantro Lime Sauce is simple. Follow these steps:

1. Prepare the Cilantro Lime Sauce: In a bowl, mix Greek yogurt or sour cream, chopped cilantro, lime juice, and salt. Set aside.
2. Cook the Black Beans: In a skillet over medium heat, add olive oil. Then, add the black beans, cumin, chili powder, garlic powder, salt, and pepper. Cook for about 5-7 minutes until heated through and slightly mashed.
3. Toast the Tortillas: In a separate skillet, toast the corn tortillas over medium heat for about 1-2 minutes on each side until they are warm and slightly crispy.
4. Assemble the Tacos: On each tortilla, add a spoonful of the black bean mixture, followed by shredded cabbage, diced tomatoes, diced red onion, and avocado slices.
5. Drizzle with Sauce: Top each taco with a generous drizzle of the cilantro lime sauce.
6. Garnish: Finish with fresh cilantro for an added burst of flavor and color.
7. Serve Immediately: Enjoy your tacos while they are warm and crispy!
