Combine ground beef, bread crumbs and egg; shape into 12 meatballs.
Bring pasta sauce to a boil in 3-quart saucepan. Stir in uncooked meatballs.
Simmer, covered, stirring occasionally, 20 minutes or until meatballs are done. Serve over hot spaghetti.
Hint...just made this again...kids loved it...and I used more pasta sauce so that there would be plenty of sauce with the noodles and and meat balls. I used a 2 lb jar. And, I made Crispy Garlic Toast to go with it!
