These sweet potato and black bean enchiladas are a delicious and filling vegetarian option. The filling is made with roasted sweet potatoes, black beans, onions, and spices, all mashed together until creamy and flavorful. The enchiladas are then rolled up in corn tortillas, topped with a smoky chipotle enchilada sauce, and baked until the cheese is melted and golden. Serve them with a side of Mexican slaw and a squeeze of lime for a burst of freshness.
