Vegetarian dishes are common. Vegan dishes are a tiny bit more rare.
- Pickle soup is a classic (use a recipe with fermented pickles, which are pretty easy to make at home, but larger grocers often also sell them refrigerated as a kosher product). Aside from the sour cream it's naturally vegan, and a vegan sour cream might work fine.
- Borscht is a delicious beet soup.
- Wild mushroom perogies are also pretty close, save for egg and sour cream in the dough. Vegan substitutes would definitely work there, else if you experiment a bit with the hydration a basic hot water and flour dough would be close.
- Cabbage soup is similar to pickle soup in spirit (using sauerkraut, another lacto-fermented vegetable).
- Placki Ziemniaczane (somewhat similar to US hash browns) is often served with mushroom sauce. Sometimes it'll have egg as a binder, but that's not essential for a very similar dish (replace it if you'd like, or add a bit more flour and water, or just leave it out).
- Braised sauerkraut
- Krupnik is a barley soup, often made with meat stocks, but vegetable stocks aren't bad either.
That's a fair callout. I think the best borschts I've eaten had dairy, but somehow I had bright purple soups in mind when I wrote that and forgot about the others.
With any luck, a vegan sour cream ought to get you to that pink classic. No promises though, and the purple version is also great.
