In a food processor, combine cooked lentils, breadcrumbs, grated carrots, minced garlic, and a variety of herbs and spices. Pulse until the mixture comes together and can be shaped into meatballs. Bake the meatballs in the oven until golden and firm. To assemble the subs, use your favorite vegetarian sub rolls, marinara sauce, and some shredded mozzarella cheese. Spread marinara sauce onto the rolls, add the lentil meatballs, and top with mozzarella cheese. Place the subs under the broiler until the cheese is melted and bubbly. These vegetarian meatball subs are packed with flavor and make a satisfying meal for vegetarians and meat-lovers alike.
