Adapted from McCall's March 1999. I've only made this on the stovetop and it came out great! It is very good on a cold winter night. I really like the fact that the onion is grated for the meatballs because I'm not a big fan of chunky onion pieces. I think instead of using the chunk of Parmesan I just sprinkled some grated cheese on top of the soup when serving but I'm sure it adds a lot of flavor when you slow-cook it. Cooking time varies depending on which method you use.
