In a medium bowl, combine the black beans, corn, cherry tomatoes, cumin, smoked paprika, and a pinch of salt and pepper. Stir well to mix all the ingredients thoroughly.
Lay out a tortilla on a clean surface. Place a handful of spinach or mixed greens in the center of the tortilla.
Spoon about a quarter of the black bean mixture over the greens.
Top with a few slices of avocado.
Fold the sides of the tortilla inward, then carefully roll from the bottom up to form a burrito. Repeat with the remaining tortillas and filling.
Optionally, you can place the burritos seam side down on a non-stick skillet over medium heat for 1-2 minutes per side to lightly toast them and enhance the flavors.
Cut the burritos in half, serve them with hot sauce or salsa on the side for dipping.
