Why these meatballs are awesome. 1. Low in fat (as they are void of any animal fats and are baked in the oven) 2. Are a great way to stock up on veggies loaded with nutrients 3. Gluten & Nut free. Make a big batch of these meatballs and the marinara sauce and use it for other recipes like the Meatball Pizza and the Meatball & Marinara Sauce Spaghetti.
