I will admit pierogi is my weak spot. Even when I do a whole Polish dinner, I often buy them, but the only ones that are really good come from a Polish deli in Bayonne, NJ. I get several dozen frozen from a cousin who lives nearby (I’m in Virginia) at Christmas and ration them for company and myself through the rest of winter. I did make vegan pierogi with my vegan daughter, and they weren’t half bad, but of course she doesn’t use farmers cheese (my favorite, so hard to find, with sauerkraut a close second?
The rest of the year I make “pierogi noodles.” Fry diced onions until soft and beginning to brown; put in a can or bag of sauerkraut, including the liquid, and season with ground peppercorns and a good amount of caraway seed. While that melds, cooks and browns,(add water to keep from burning but allow it to brown), boil a cup or more of rotini until soft, drain and add to the pan. I used to put the whole mixture in the oven for a half hour or so but now I just let it all sit in the pan. It is sooooo good, and has been a pandemic staple for the past year or more.
Pssst… farmers cheese is not that hard to make. 
Here is a good spot to look:
