Heat an oven to 220C (fan ovens). If you are using a pizza stone, place it in the oven.

Put all the ingredients for the crust into a food processor and process for 2 - 4 minutes (depending on your machine) on a 'dough kneading' setting.

On a floured surface knead the dough for a minute or so to combine it well. (If you put a bit of oil on your hands the dough will not stick to them).

Divide the dough into 2 parts and form pizzas (you can either roll them or stretch).

Move one pizza base on the stone or a baking tray covered with parchment paper.

Spread half of the tomato sauce on the base, put in the hot oven and bake for approx. 15 min.

Take it out from the oven; put on top pieces of prosciutto, arugula and Parmesan, sprinkle with a dash of olive oil.
