This is the perfect summer appetizer or addition to your meal to showcase fresh tomatoes and herbs. Use the best tomatoes you can find, grape tomatoes cut in 4 also work well with less water content. Use fresh or dried herbs, whatever is handy. Mix the topping ahead of time and store in the refrigerator. You can also toast the bread before hand so that when your guests arrive you just have to top the bread and broil for a few minutes.
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.
