Add the oil and mix with your hands or with the help of a spatula.
Add the water little by little until a homogeneous mixture is formed and does not crumble.
Roll out the dough on waxed paper with a rolling pin.
Sprinkle salt over the dough and use a knife or pizza cutter or a cookie cutter to divide the dough into pieces no larger than 2 cm.
