Preheat oven to 375°. In a large bowl, combine eggs, water, onion, bread crumbs, Parmesan cheese, garlic and seasonings; mix well. Crumble beef over mixture and mix well. Shape into 1-1/2-in. balls. Place meatballs on greased racks in shallow baking pans. Bake, uncovered, until no longer pink, 15-18 minutes.
Freeze option: Freeze cooled meatballs in freezer containers. To use, partially thaw in refrigerator overnight. Heat through in the microwave.
