Then turn the meat, jerky meat, onion, parsley and the squeezed out bun through the meat grinder. Always alternate the individual ingredients so that a fairly even mixture is created.
Season with salt and pepper and mix in the 2 eggs. If the mixture is too moist, add some breadcrumbs.
Shape meatballs and fry them.
Personally, I prefer this type of meatball to the classic one from Hack, but everyone has to decide that for themselves.
In any case, it is a good use of leftovers for the soup meat.
