In a blender, combine the cooked black beans, vegetable broth, cumin, garlic powder, salt, and pepper; blend until smooth.
Heat a non-stick skillet over medium heat.
Dip each tortilla into the black bean sauce, ensuring both sides are coated.
Place the coated tortilla in the skillet for about 30 seconds to warm it up.
Remove the tortilla and place it on a plate.
Add a spoonful of the bean mixture onto the tortilla and fold it in half.
Repeat with the remaining tortillas.
Drizzle additional bean sauce over the top of the filled tortillas.
Garnish with crumbled queso fresco, sour cream, and chopped cilantro.
Serve hot with sliced radishes and jalapeños on the side.
