Preheat your pizza oven according to the manufacturer's instructions. Typically, the oven needs to be preheated for about 15-20 minutes to reach the correct temperature.
Divide the dough into the desired number of portions (usually one portion per pizza) and shape each portion into balls of at least 250 g.
Let the balls rest and rise for about 15-20 minutes under a cloth.
When the oven is sufficiently preheated, gently stretch each dough ball into a thin pizza base by pressing the dough flat with your fingers and working from the center out to the edges.
Place the stretched dough on a pizza peel or a lightly floured surface.
Spread an even layer of the previously prepared pizza sauce over the stretched dough.
Sprinkle grated Parmesan cheese over the sauce.
Distribute fresh mozzarella cheese in smaller pieces evenly over the Parmesan and sauce.
If using salsiccia, remove the sausage meat from the casing and crumble it over the pizza.
Drizzle a little olive oil over the pizza and sprinkle with a pinch of sea salt.
Carefully slide the pizza from the peel into the hot pizza oven and bake for about 2-3 minutes or until the crust is golden brown and the cheese is melted and bubbling.
Use a pizza peel to remove the pizza from the oven and place it on a baking sheet or cutting surface.
Once the pizza is out of the oven, add fresh basil leaves and extra olive oil on top.
Cut the pizza into slices and serve immediately.
