Combine bread pieces with 2/3 cup water and set aside 5 min then mash with a fork.
In a large mixing bowl add: 1 lb ground beef, 1/4 cup parmesan, 4 minced garlic cloves, 1 tsp salt, 1/2 tsp black pepper, 1 egg and mashed bread crumbs. Mix until well combined.
Form into 1 1/2″ meatballs (about a flat ice cream scoop of meat). Dredge/roll meatballs in flour, dusting off excess. Heat a deep, large, heavy skillet or a Dutch oven over medium heat with about 3 Tbsp oil. Add meatballs in 2 batches without crowding the pan and saute until browned on all sides (about 6 min total or 2 min per side). Remove meatballs and set aside
