>> There are also different opinions on the term vegetarian. In Sweden, it commonly includes milk and egg, and if you order a vegetarian pizza you get cheese from cow milk.

In My Big Fat Greek Wedding there's a scene were the mother-in-law learns the groom is vegetarian and (after exclaiming embarrassingly loudly) she says she'll cook him lamb:

The way I understand this is that it says that Greeks think that lamb is vegetarian as in "not really meat". I always found that a little weird, because in Greece lamb is absolutely "meat". Traditionally, you're only supposed to eat it on Easter sunday, or on religious feasts (the "panygiria") so it's really something special, unlike pulses, legumes and fish (which would be eaten much more commonly traditionally). I can imagine a Greek yiayia saying "You're vegetarian? That's OK, I'll cook you chicken!", or adding feta to the salad, etc. But- lamb? I don't quite see that.

Maybe it's a Greek US diaspora thing, but I'm guessing that was translated for the American audience whom the authors considered might be confused by "I'll cook you chicken", because they actually don't consider chicken to be "meat".
