In a large mixing bowl, combine black beans, corn, cumin, chili powder, garlic powder, salt, pepper, and half of the shredded cheese. Stir until well mixed.
Slice the zucchini lengthwise into thin strips, about ¼ inch thick.
Lay zucchini strips on a baking sheet, spoon the filling onto each strip, and roll them up, seam-side down in a greased baking dish.
Pour the enchilada sauce evenly over the top and sprinkle the remaining cheese.
Bake for 30 minutes until the cheese is melted and bubbly.
Garnish with chopped cilantro before serving.
