Lasagna is a classic Italian dish that is typically made with layers of pasta, meat sauce, cheese, and vegetables. While lasagna can be a delicious and satisfying meal, it can also be time-consuming and labor-intensive to make. This easy vegetable lasagna recipe is a great way to enjoy all the flavors of lasagna without all the hassle.
