It looks like a piadina, but a crescia sfogliata of Urbino, the favourite of the Renaissance Dukes of Montefeltro, is more complicated and 'rich' using black pepper (which was very expensive back in the 15th century) as well as eggs, yeast, milk, pepper, and lard, then fried in a frying pan. Popular fillings include rocket and squacquerone, prosciutto, sautéed spinach etc.
