Combine bread flour, salt, olive oil, and yeast.

Add lukewarm water and mix to form a dough.

Let the dough rest at room temperature for at least 30 minutes, until it doubles in size.

Punch down the risen dough to release air.

Lightly dust the work surface with flour.

Roll out the dough to a thickness of 0.5 cm.

Use cookie cutters to cut out shapes from the dough.

Preheat the oven to 200C (392F).

Place the dough shapes on a baking sheet.

Spread a spoonful of tomato sauce on each dough shape.

Sprinkle cheese over the tomato sauce.

Add your desired toppings.

Bake in the preheated oven for 10-15 minutes, or until golden brown and the cheese is melted.

Let cool slightly before serving.
