I just got given a nice bowl of Schi by my girlfriend's Mamochka, and slabs of pork with a very nice mushroom salad, so I'm voting Russian.
I do love a bit of Gulash though, so additional congratulations to the Magyars! The dumplings in a Czech themed place in town are lovely too, so the Czechs can have an honourable mention too. I like proper stodgy food.
The English can't be beaten for pies and sausages though! Or cakes...
