Step 1

In a large bowl, combine the first five ingredients. Crumble the meat over mixture and mix well. Shape into 2-in. meatballs.

Step 2

In a large skillet, brown meatballs over medium heat until a thermometer reads 160°; drain. Add spaghetti sauce; bring to a boil. Reduce heat; simmer, uncovered, for 20-30 minutes or until heated through. Serve with spaghetti; sprinkle with cheese if desired.
