A delicious and easily made meatball and sauce dish stuffed with mozzarella cheese.
Combine all sauce ingredients in slow cooker and stir. Set to high and cover while making meatballs, or for 30 minutes. (Or use pre-made/canned sauce.)
Combine all meatball ingredients except the mozzarella in a large bowl. Using your hands, mix until fully combined.
Take a golf ball sized piece of the ground beef mixture and place a piece of mozzarella in the middle. Press meat around the piece of cheese, fully enclosing it. Repeat until all meat is used.
Place meatballs in slow cooker and submerge in sauce.
Cover and cook on high for 2-2½ hours, or until meat is fully cooked.
Serve by itself or over pasta.
