Combine the mince, oregano, fennel seeds and some seasoning in a bowl. Take walnut-sized pieces of the mixture and roll into balls. Heat half the oil in a large, shallow ovenproof pan and cook the meatballs until browned all over – don’t worry if they’re not cooked through. Transfer to a plate. Heat the oven to 200C/180C fan/gas 6.

Heat the remaining oil in the pan and add the onion. Cook until softened, about 10-12 mins, stirring regularly. Stir in the garlic for another minute, then the tomato purée, chopped tomatoes and sugar.

Simmer for 10-15 mins, then season to taste. Place the meatballs on top of the sauce, then add the mozzarella, garlic bread and the cheddar on top. Bake for 15-20 mins until golden and crisp.
