In a medium mixing bowl, combine ground beef, cheese, bread crumbs, egg, garlic and salt. Mix well. I typically use my hands as I feel like they come out best that way.
Shape into meatballs about the size of a golfball and place on a cookie sheet.
Cover with foil and let rest in the fridge for about an hour.
When ready to cook, bring sauce to a gentle simmer in a shallow pot. I like to use one that allows me to cook the meatballs in one layer with them mostly covered by sauce.
Add meatballs, cover and cook on low for about 45 minutes until cooked through, stirring occasionally.
Serve over pasta or on rolls for meatball sandwiches.
