Preheat your oven to 200°C
Cut the Mozzarella Cheese into cubes, about 1x1cm
In a large bowl, mix the Mince, Breadcrumbs, Egg, Garlic, Onion, Salt, Pepper, and Italian seasoning until just combined.
Using your hands, roll the mixture into balls, about 4cm’s in diameter, inserting a piece of Cheese into the centre of each Meatball, enclosing completely with the mince.
In a large oven-safe pan, heat a drizzle of Olive Oil over medium heat cook the meat balls to seal, browning them on all sides
In the same pan, pour in the Passata sauce to cover and cook on low, simmering for 15-20mins, or until the Meatballs are cooked through
Remove from the oven and spoon onto sliced Baguette
