Mix bread crumbs, egg, water and wheat germ into a medium mixing bowl. Then, add salt, pepper, ground beef, pork, and sausage and mix. Shape into small balls. Place meatballs in spaghetti sauce and allow to cook for 2 to 3 hours.
Mom's Spaghetti Sauce:
In a large saucepan over medium heat, saute the ground beef, pork and sausage until it is brown. Drain off excess fat. Add the remaining ingredients and stir until smooth. Cook for 3 to 4 hours on medium heat, stirring often to prevent scorching.
