Portobello mushrooms are the star of these rich and flavorful enchiladas. The mushrooms are sautéed until tender and then combined with onions, garlic, and spices. The mixture is then rolled up in tortillas and topped with a tangy enchilada sauce and melted cheese. Baked until the cheese is bubbly and golden, these enchiladas are a delicious and satisfying option for mushroom lovers and vegetarians.
