Soparnik
Soparnik is a traditional Croatian dish. It is usually a savoury pie with a filling of Swiss chard. Other names are soparnjak, zeljanik or uljenjak. It is the most famous speciality of the Dalmatian region of Poljica, between Split and Omiš. The original season for the dish was the colder time of the year when older, sweeter chard was available. Basically, it is a very simple dish made from common ingredients from the region: Chard with onions and parsley between two layers of simplest dough. Among the numerous local variations there are also sweet ones, for example with nuts, dried fruits or caramel.
