Sprinkle a large shallow baking pan with a little corn flour and place the pizza crust in it.
Spread the pizza crust with your fingers so that it covers the whole baking pan surface and it becomes very thin.
Use a spoon to spread the thick tomato sauce circularly all over the pizza surface.
Spread the salami, olive slices and feta cheese all over. Sprinkle with the oregano, basil and a few drops of olive oil.
Preheat the oven at 200°C, with extra heat on the top and bottom oven elements, and use the bottom rack.
Place the pizza in a hot oven and bake it without opening and closing the door for approx. 25 min, until the pizza bottom is well baked.

For the quick tomato sauce:
Add all the materials in a small saucepan and boil for 10 min. While boiling, stir a few times to help break and melt the tomatoes.
The quick tomato sauce must be very dry, without any juices. Keep any excess sauce in the fridge inside a sterilized glass jar, where it will keep for several days. For better conservation, cover the sauce surface with olive oil.
