Dissolve the yeast in the water then pour it into a bowl and add the semolina and salt.
Knead well, forming a ball and leave to rest for an hour.
Then take the dough and divide it into 4 pieces, roll it out and form pizzas, oil them and massage them with your fingertips.
Heat the oil in a frying pan, arrange the pizzette and cook with a closed lid for 5 minutes.
Turn them over and cook for another 5 minutes or so and sprinkle with oregano.
Enjoy them with some sauce or seasoning to taste.
