Having a Grandfather from the Ukraine and a Grandmother from Poland the meals at my house always included those comfort foods.
The Ukrainians or Russians called the (Polish) pierogi VARENIKI
Golumki or GOLOBKI (Polish stuffed cabbage) were called GOLUBTSI (with a soft G) or as use kids would call them Halupsi.
Kraut was always referred to as Kapusta and was cooked with garlic and bay leaves (in butter or fat of course) until it was so tender that it melted in your mouth.
After making the regular (sauerkraut-cheese-potato) varieties there was always a pot of blueberry varenikis that served as dessert along with Cheese Blini or blintzes.
Add a few pounds of kielbasi, a plate of potato pancakes, a loaf of sour rye all served with a big pot of sour cream and you have a Carb diet that would be outlawed in most States.
