Transfer the risen dough to a floured surface. Divide it into three or four equal parts (depending on how thin you like your pizza, I prefer it divided into four parts). Roll each one out to a 30 cm diameter, transfer it to a baking sheet, spread 2 tablespoons of sauce on it, sprinkle 150 grams of grated mozzarella, arrange pepperoni slices on top, and sprinkle with 1/2 teaspoon of oregano.
