Begin by gathering all your ingredients to streamline the process. Rinse and drain the canned black beans, chop the onion, and finely dice the cilantro. Warm the tortillas in a dry skillet over medium heat for about 20-30 seconds per side.

Mash the avocado in a large bowl until creamy, leaving some chunks for texture. Stir in the prepared black beans, onion, cilantro, chili powder, salt, and pepper until well combined.

Lay a warm tortilla flat and spoon a generous amount of the filling onto the center. Fold the sides toward the center, then roll the tortilla tightly from the bottom up.

Cut the burritos in half for easier handling or serve whole. Enjoy immediately with your favorite salsa or guacamole.
