While your sauce is simmering, take your ground beef and make 4 meatballs that are about 1 inch wide. After the 5 minutes of your sauce simmering, add in the meatballs and stir the contents to spread the flavor. Cover again for 10 minutes, stirring occasionally.
Note: When stirring, try to roll the meatballs and sauce together as much as possible to soak the flavors together.
