Preheat the oven to 200°C (180°C fan) or gas mark 6.

Wet your hands, push a piece of mozzarella into the center of each meatball, then re-form the meat around it to enclose the cheese.

Arrange the stuffed meatballs on a baking tray and cook for 15-20 minutes, until browned and cooked through.

Meanwhile, pour the tomato and basil sauce into a pan and gently heat, allowing it to bubble and reduce slightly.

Once the meatballs are cooked, place a mini skewer in each one and serve with the warm sauce for dipping.
