Loaded Portobello Mushrooms are a delicious and hearty vegetarian dish. The large portobello mushrooms are stuffed with a flavorful mixture of sautéed vegetables, breadcrumbs, and cheese. They are then baked until the mushrooms are tender and the cheese is melted and golden. These loaded mushrooms make a great appetizer or main course and are perfect for a meatless meal. Serve them with a side salad or crusty bread for a satisfying and nutritious dish.
