Help! My Italian meat are always tough/chewy!?

You've got way too much egg in there, cut back to 1 and up the breadcrumbs and parm cheese to 1/2 cup each. Next do NOT over mix the meat, that's another thing that toughens it up. Mix just until the ingredients are combined. If that doesn't help you may have to use a cheaper, fattier grade of ground meat. Lean beef can by dry and tough.
