Piadatina is a traditional Italian dish that originated in the Emilia-Romagna region. It is a type of flatbread that is typically made with a simple dough of flour, water, yeast, and salt. The dough is then rolled out thinly and topped with a variety of ingredients such as cold cuts, cheese, and vegetables. The piadatina is then folded into a half-moon shape and baked until crispy. This dish is often enjoyed as a quick and convenient meal or snack, and is popular in Italy as well as in other parts of the world.
