These Sweet Potato Enchiladas are a delicious and satisfying vegetarian dish. The sweet potatoes are roasted until tender and then mashed with black beans, corn, and spices. The mixture is then rolled in tortillas, topped with enchilada sauce and cheese, and baked until bubbly and golden. Serve with a dollop of sour cream and a sprinkle of fresh cilantro for a flavorful and comforting meal.
