This pesto veggie lasagna is a fresh and flavorful take on the traditional dish. Instead of using a tomato-based sauce, this recipe calls for a homemade basil pesto sauce. The pesto is made with fresh basil, garlic, pine nuts, Parmesan cheese, and olive oil, creating a vibrant and aromatic sauce. The lasagna is layered with sautéed vegetables such as zucchini, bell peppers, and mushrooms, along with a creamy ricotta and mozzarella cheese mixture. The result is a light and summery lasagna that is bursting with flavor.
