pierogi
Pierogi (noun) means a dumpling of plain dough, shaped like a square or crescent, filled with something such as cheese, potato, cabbage, meat or fruit.
Etymology
Borrowed from Polish pierogi, the plural of pieróg (“dumpling”), which ultimately is derived from Proto-Slavic *pirъ (“party”). Relationship to Turkish börek is unclear. Doublet of pirogi (from Russian), pirohy (from Czech and Slovak), and pyrohy/pedaheh (from Ukrainian).
