I am a big fan of sushi. Are you?
yea sushi can be prepared with either brown or white rice
I see, do you have it with any sauce?
it is often served with pickled ginger, wasabi, or soy sauce
I see, I like it with Wasabi. Do you have it raw or cooked?
it is often prepared with raw seafood, but some people used cooked sushi
I am one of those that like it cooked because raw sushi can cause stomach cramps!
some people confuse sushi sashimi, a related japanese dish consisting of thinly sliced raw fish
Oh yes I can see why it might be confusing. They both sound very similar. 
sushi became an important source of protein for its japanese consumers
