Mix flour, 1/2 teaspoon salt and yeast. Knead with 200 ml lukewarm water and 2 tablespoons of oil with the dough hooks of the hand mixer, then smooth by hand. Cover and leave to rise in a warm place for about 40 minutes.
In the meantime mix tomato paste and 3-4 tablespoons of water. Season with salt, pepper and ##oregano##. Drain ##mozzarella## and cut into slices.
Knead the dough again. Divide into 3 pieces. Roll out to pizzas (approx. 26 cm Ø) on a little flour. Place on baking trays lined with baking paper. Spread with tomato paste.
