Bread and filling. Nothing more ancient, practical, substantial, good. The tradition of stuffing slices of bread dates back to the mists of time. Greek philosopher Diogenes of Sinope is often described in the act of eating lentils in a hollowed piece of bread.

The sandwich, however, seems to have taken hold more massively in Rome: the name of via Panisperna derives from the Latin phrase panis ac perna, bread and ham, a very popular snack at the time, consisting of a loaf of bread made with wine must, ham and dried figs.
