Vegetable lasagna is a delicious and satisfying Italian dish that is perfect for vegetarians. It is made by layering lasagna noodles with a mixture of sautéed vegetables such as zucchini, spinach, mushrooms, and bell peppers, and then topping it with marinara sauce and cheese. The lasagna is baked until the cheese is melted and bubbly, resulting in a hearty and flavorful dish that is loved by both vegetarians and meat-eaters alike.
