Take the dough out and squash to knock out the air. Roll out on a floured surface to fit the largest baking tray you have. Sprinkle flour or semolina over the tray, then place the dough on top. Spread the tomato sauce over the dough, then scatter with the salami, peppadews, onion, chilli flakes, mozzarella and oregano. Bake for 12-15 mins or until the dough turns crusty and golden.
