Spaghetti and Meatball Casserole

Here is another version of spaghetti casserole but with meatballs. These meatballs really steal the show as they are packed with flavour. We like our food hot so I used hot Italian sausage meat but you can use mild and it will be flavourful as well. The fresh mozzarella melts so nicely and adds so much to the casserole. Enjoy!
