I'm little confused here. Seems you're referring to American http://en.wikipedia.org/wiki/Pigs_in_a_blanket but that's different form Polish http://en.wikipedia.org/wiki/Go%C5%82%C4%85bki. As you can see, go??bkis are wrapped in a cabbage leaf, not in a pastry thing. http://translate.google.pl/#pl%7Cen%7Cgo%C5%82%C4%85bki should help with pronunciation, just click on the speaker icon on the left window, though the accent is a bit weird.
I've used to eat a lot of pierogies as a child. I've only liked these with http://farm3.static.flickr.com/2138/2435066506_60b12ac9eb.jpg as a filling, but they can also be filled with cabbage, meat or mushrooms.
PS. sorry for what? If you mean that I have to answer all this, then that's no problem! Never too much of training myself in English.
I actually am referring to traditiional Polish Golabkis (not sure how to put the accents/diacritic marks in). Americans call them "Pigs in the Blanket", even though they are 2 very separate things. I agree with you in that when I hear "Pigs in the Blanket" I think of the little hot dog hor'dourves as well. Anyway, seems that only in Eastern European ethnic neighborhoods do they actually get called "Golabkis".
I only ever really eat Potato Pierogies. They are the most common here. Sometimes, you can find sauerkraut or cottage cheese, but I've never seen meat or mushroom.
Just saying that you probably didn't expect to get bombarded by Polish Questions. I've been waiting for someone to come around.

Your English is very impressive, by the way.
I'll PM you for that recipe you mentioned.
