I did something like this last year
Porkchops (most any pork will do) marinated in sour cream I think? Cooked with more sour cream, onion, garlic,and paprika?It was suppose to have some whitewine also. It was make into a gravy or sauce of some sort and served like that.
I think that some sauerkraut could be mixed in. There are some frozen perogis in the freezer that need to be used and would well with this.
