Place breadcrumbs in a bowl with warm water allow to soak for a few minutes. In a large bowl add beef, pork, eggs, cheese, seasonings, onion, parsley and tomato sauce. Mix a few times and then add breadcrumbs ( make sure you squeeze out excess water) and mix until everything is incorporated. Roll into equal sized balls and place on a baking sheet freeze for 1 hour. Than transfer into a bag and freeze for up to 3 months.
