First, prepare the toppings. Instead of ham or salami you can use 10-12 anchovy fillets or some other type of oil preserved fish.
Sift the flour with the baking powder. Knead a dough from the listed products. Roll it out in a buttered and flour tray. Put it to bake in the oven until reddened.
Take it out and smear it with the tomato blend. On top, arrange salami/fish, the garlic and grated cheese. Put it back in the oven until the pizza gains an appetizing crisp.
