Add 3 meats to a bowl. Half a pound ground beef, a quarter pound ground pork, a quarter pound ground veal. Mix by hand until combined.
In a second bowl, whisk together 1 egg, 4 cloves garlic grated, one half of a white onion grated, 3 tablespoons extra virgin olive oil, 6 tablespoons whole milk ricotta cheese. Whisk until thoroughly combined.
In a third bowl, combine 2 tablespoons chopped parsley, one half cup Pecorino Romano cheese, 1 and one half cups seasoned Italian breadcrumbs, 2 teaspoons salt, 2 teaspoons pepper, 1 tablespoon granulated garlic, 1 tablespoon granulated onion. Mix well.
Stir the wet bowl once more. Pour it into the meat. Mix by hand until it looks like one uniform mixture without streaks.
Pour about half of the dry mixture into the meat. Mix it in evenly until it starts to firm up. Add the remaining dry mixture and mix until evenly distributed.
Cover the meatball mixture. Refrigerate for about two hours.
