I'm not familiar with pierogi, but I'm over here googling recipes. <3 Looks like something I would totally love to eat. You might have to give me some ideas here, there are a lot of different recipes for this.
I eat potet klubb bland with a side of broccoli. However, if you were to make the balls small, you could toss them into a vegetable, pork, or beef soup.
We always make a lot of potetklubb (potato dumplings), we have a tradition of slicing them thin in the morning and frying them up for breakfast. Either way, this food is extremely filling and if you aren't a potato demon, it's not yummy. lol.
I live in a small town in Oregon state, our restaurants are almost entirely Mexican cuisine. I would love it if something more exciting moved into our area.
