A nation's soul is in its food?

Having recently moved to Jozi after a youth in KZN and then 8 years in Cape Town I have thoroughly enjoyed catching up with many long lost mates. Whenever I bump into someone though I can virtually guarantee that the conversation will end with:"Cheers, we must have a braai sometime." I'm not sure whether this indicates something specifically about me or if it's something that afflicts all Joburgers, whites or South Africans in general.
