• Preheat the oven to 200°F. Wrap tortillas in aluminum foil and set them in the warm oven while you prepare the black bean taco filling.
• Set a large skillet over medium heat and add the olive oil. When the oil is hot, add the onion. Cook the onion, stirring frequently, for 3 minutes, until softened.
• Stir in the black beans, garlic powder, chili powder, and ground cumin. Use a potato masher or a fork to mash the black bean mixture slightly to your desired consistency (a little chunkiness is good).
• Stir in the salsa verde, then reduce to low heat. Cook for 5 minutes to heat through.
• Spoon the black bean filling into warmed tortillas. Add your favorite taco toppings and serve.

Crispy Black Bean Taco Option:

• To make crispy black bean tacos, wipe out the skillet and reheat with a little oil over medium-high heat. Cook the bean-filled tacos for 2-3 minutes on each side until they are golden and crispy.
