Mix flour with salt and prepared yeast.
Knead the dough, cover with a cloth, then set aside for 10 minutes.
Add olive oil to the dough, and knead the dough again.

When the dough has risen, warm up the oven to 230 degrees.
Roll out the dough on a pastry board sprinkled with flour.
Bake with your favourite addons for around 15 minutes.
Sauce:
Mix all the ingredients. Optionally, the sauce can be warmed up to evaporate part of the water.
Tomato paste can be replaced with tomatoe passata.
