There's something weirdly universal about pierogi ruskie. I've not met anyone not liking them. Actually everyone I introduced to them loved the taste. (people usually try to look up polish delis / kitchens in the area that sell them afterwards) Given the simplicity of the ingredients, that's really impressive.
polish person here, i don't like them sauerkraut+mushrooms pierogi are the best
In the US, cheese and potato is pushed instead because it's cheap as fuck to produce. Basically they end up in supermarket shelves next to all the prepared foods that are 99% cheese and 1% meat at best.
