Ingredients:
Roast Sweet Potatoes: Preheat oven to 400°F. Poke sweet potatoes with a fork and bake for about 1 hour until tender. Let cool, then scoop out the pulp.
Prepare Filling: Mix sweet potato pulp with black beans, cheeses, green chiles, jalapeño, garlic, lime juice, cumin, chili powder, cayenne pepper (if using), salt, and pepper.
Assemble Enchiladas: Pour half of the salsa verde into a baking dish. Fill each tortilla with the sweet potato mixture and roll up. Place seam-side down in the dish. Pour the remaining salsa verde over the top.
Bake: Cover with foil and bake at 375°F for 15 minutes. Remove foil and bake for an additional 10-15 minutes until hot and bubbly.
