For a healthier twist on the classic meatball sub, try making it with turkey meatballs. Ground turkey is mixed with breadcrumbs, egg, onion, garlic, and a variety of herbs and spices to create flavorful and moist meatballs. These turkey meatballs are then baked in the oven until cooked through. To assemble the sub, use a whole wheat baguette or sub roll, layer with sliced mozzarella cheese, add the turkey meatballs, and top with marinara sauce. You can also add some sautéed bell peppers and onions for extra flavor and crunch. Bake in the oven until the cheese is melted and the sub is heated through. This turkey meatball sub is a healthier alternative that doesn't compromise on taste!
