Whisk together Italian Seasoning and breadcrumbs in large mixing bowl. Stir in milk; let stand 10 min. Add meat and egg to bowl; thoroughly mix using your hands until well blended (do not overmix). Form 20-22 (1 ¾" to 2") balls using slightly wet hands. Arrange meatballs on parchment paper-lined baking sheet; bake in preheated 400° oven until done (about 25 min.).
Good to Know: If desired, freeze meatballs in a single layer up to 2 months. To serve, thaw up to 36 hrs. in refrigerator.
