Throughout the towns of Emilia-Romagna are little food stands, where piadina (flat bread) is grilled to order and sandwiched around a variety of fillings, like cheese and prosciutto. Paul Bartolotta describes piadina as Italy's defense against fast food—while it's fast to make, it's real food with a cultural past. His version is hearty and irresistible, especially when sandwiched with milky, fresh ricotta cheese, salty prosciutto and a vibrant arugula salad.
