We use have them out of a tin!
I was inspired by the recipe in the paper today. I have made meatballs before and I had most of the ingredients in so it seemed a nice idea . I didn't soak the bread just loosed the mixture with some of the pasta sauce (a tip I read about in a Scorsese's interview!) oh and I included some smoked bacon in the meatball mix which I cooked with the onions. It's a good little recipe.
ps. Didn't have any Parmesan and I rather like cheddar.
