I'm Lithuanian on my father's side -- we have pierogi, too! Only in Lithuanian -- the word is something like vittini (no one's quite sure how to spell it). I'll be making them for Christmas: most with my family's traditional filling of bacon, mushroom and onion; and some with my niece's favorite filling of mashed potato mixed with sour cream and cheese. The whole family (and friends) love them -- me, too, but they're lot of backbreaking work!
Ah, pierogi Litwa :-) —> I like them too, but man, those are heavy! Now you’re making me feel hungry!
