Tomato Sauce with Meatballs

Because this sauce is so divine the recipe makes a double batch.  A double batch can be made by each guest but requires a 7 litre/7 quart slow cooker or dutch oven.  In a group setting it is suggested that 2 guests make one recipe just divide vegetables and sauce between 2 pots and guests can roll their own meatballs. This recipe works well started in the morning and cooking in the slow cooker for 6 hours on high or simmering on the stove for 3 hours.  Flavours are fantastic made a day ahead.
