Pierogi

Jarod Carruthers has added a photo to the pool:

From Wikipedia: Pierogi (Polish pronunciation: [pjɛˈrɔɡʲi]; also spelled perogi, pierogy, perogy, pierógi, pyrohy, or pyrogy) are dumplings of unleavened dough – first boiled, then they are baked or fried usually in butter with onions – traditionally stuffed with potato filling, sauerkraut, ground meat, cheese, or fruit. Of central and eastern European provenance, they are usually semicircular, but are rectangular or triangular in some cuisines.
