I love cheese sticks and cheese balls on the appetizer menu in restaurants and this is a way to take everyday macaroni and cheese and turn it into cheese balls, which are baked rather than fried. Don't skip the step of using well-chilled mac 'n cheese prior to baking them because you want the cheese to melt in your mouth, not all over the baking sheets. I promise these crispy 'n crunchy yet soft 'n gooey cheese balls are worth the wait.
