Add the flour and the salt to a large bowl and give a quick mix.
Add the water and the oil and start mixing everything with the large spoon.
Continue mixing and kneading with your hands inside the bowl and then transfer the flour to the pastry board.
Once on the board, keep kneading for some 10/15 minutes until you have a smooth dough without lumps, slightly elastic and easy to work.
When ready, cover it for about 30 minutes to an hour to rest and settle.
When the resting time is over, go back to your dough and give it an elongated shape similar to a loaf. Cut it into 4 to 6 pieces.
Give each piece a round shape and set them aside while you work on each of them.
Grab your rolling pin and make flatbread of around 5 mm out of each piece, giving them a shape as round as possible.
Heat up a non-stick pan or even better a grill pan specifically for flatbread. Once it's very hot, place the first piadina and cook it for roughly a minute on each side.
Remove it from the pan and cover it with a kitchen cloth before moving on to the next piadina to cook. Once ready, place all the piadina on top of each other under the kitchen towel.
