Although they were invented in Lithuania, potato zrazy are traditional Ukrainian dish - Ukrainians substantially changed and enriched the recipe.
Ukrainian zrazy are stuffed potato. The filling can be different: meat, cabbage or mushrooms. Along with majority Ukrainian dishes zrazy are very rich, therefore, 2-3 pieces are enough to satisfy hunger pangs for a long time.
Zrazy are traditionally served with sour cream or tomato sauce for dinner or supper. It's not recommended to eat this dish for breakfast, because it is quite caloric and hardly digestible for yet sleeping organism.
