Meatball and pepperoni pizza

Method

1. Heat a splash of the olive oil in a deep frying pan. When hot, add the meatballs and fry on a medium heat, turning occasionally, until well browned all over (4-5 minutes). Set the meatballs aside on a plate, then add the remaining oil to the pan along with the garlic and gently warm through for a minute.
2. Add the passata to the pan along with the vinegar, oregano and chilli flakes, then stir and let the sauce simmer for 10 minutes. Return the meatballs to the pan and simmer again for 8-10 minutes until the meatballs are cooked through. Set aside (see Make Ahead).
3. Meanwhile, heat the oven to its highest setting. On a well-floured work top, roll out each ball of dough to a circle roughly 20cm in diameter, then transfer them to 2 lightly dusted baking sheets.
4. Spoon some meatball sauce (see tip) onto the pizza bases and spread evenly, then scatter over the mozzarella, sausage, pepperoni, green pepper and onion. Bake for 8-10 minutes until crisp and golden. Sprinkle with extra oregano and a pinch of chilli flakes to serve.
