Pour the flour, the yeast, salt, the oil and the water in a large bowl and stir it first with a knife to mix solid with liquid ingredients. Then knead with hands until you get a dough soft and elastic that does not stick. Shape it like a ball and leave it covered for 30 '.
Spread with oil the large oven baking dish (the dough reaches for it) or smaller ones, if you like more (smaller) pizza bases. Put the fluffy dough into the pan and spread it with your hands to cover the bottom and some of the side walls. Let it for more 15' minutes covered aside.
Grease lightly the surface of the dough, spread the tomato sauce, the cheeses or the cold cuts you prefer and bake in preheated oven (200 ° C) for 30 minutes or so (maybe a little less or a little more depending on the oven).
