Vegetarian lasagna can be a very healthy choice if it is not made with white pasta, which contains no fiber. Other factors that help determine the healthiness of vegetarian lasagna include the amount of cheese and vegetables in the dish.
Healthy vegetarian lasagna can be made by using a tomato-based sauce and a small amount of traditional Italian cheese. Whole wheat noodles make lasagna healthier than the white pasta raditionally used in lasagna recipes. Good vegetables to include in a vegetarian lasagna include bell peppers, spinach, red onion, zucchini and crushed tomatoes. Use fat-free ricotta cheese and low-fat mozzarella to make it even healthier.
