1 lb. lean ground beef
1 egg
2 tablespoons water
1/2 cup bread crumbs
1/4 cup minced onion
1/2 teaspoon salt
1/8 teaspoon pepper

Preheat oven to 350 degrees. In large bowl combine egg, water, bread crumbs, onion, salt and pepper and combine. Add ground beef, broken into chunks, and use your hands to combine. Form into meatballs about 1" in diameter and place on a broiler pan. Bake at 350 degrees for 25-30 minutes until meatballs are no longer pink in center. Cool and freeze, or serve with pressure cooker marinara sauce.
