Preheat the oven to 350 degrees F.
Combine the ground meat with the eggs and mix well. Add the meats and breadcrumbs to a small mixer and combine well. Add the Parmesan, dried parsley, garlic powder, salt and pepper and mix on medium speed, 3 minutes (do not over mix). Scoop out 18 meatballs, using an ice-cream scoop (or forming the meatballs to ice-cream-scoop size). Mix the mozzarella, capicola, provolone, ham and salami in a mixing bowl. Stuff each meatball by making a hole in the middle and placing 1 tablespoon of the meat-and-cheese mixture in the center. Seal the meatballs well by pinching them back together. Bake, covered with foil, 45 minutes.
