Sweet potato and black bean enchiladas are a hearty and nutritious vegetarian option. The filling is made with roasted sweet potatoes, black beans, onions, and spices like cumin and smoked paprika. The enchiladas are then topped with a homemade red enchilada sauce and cheese, and baked until the cheese is melted and golden. Serve them with a side of avocado salsa and a squeeze of lime for a burst of freshness.
