In a large bowl combine the beef, pork, ½ cup panko bread crumbs, milk and eggs and set aside. In a food processor, combine the parsley, basil, garlic, olive oil, parmesan and pine nuts. Process for 30-45 seconds until almost pesto like. Add the herb mixture to the meat and mix until evenly combined. Season with salt and pepper. Shape the meatballs into large balls then roll them in the remaining panko bread crumbs.
