 Other fillings are onions sauteed in olive oil and seasoned with salted anchovies and capers or mortadella and provolone cheese.A different recipe for panzerotti is "panzerotti di patate" ("potato panzerottis"), a specialty from Salento which consists of mashed potato croquettes rather than panzerotti as the term is most typically intended.Panzerotti are also consumed in North America, where they were imported by Southern Italian immigrants at the time of the Italian diaspora.
