Sushi for lunch?? That's what I had for lunch today with my colleagues. They were giving me the 'what are you doing' look when I place the wasabi in the saucer of soya sauce and mixed them all up. Apparently, what they do is to spread a bit of wasabi on top of the sushi and then dip the sushi in the soya sauce.

Sounds the same to me, except that I was being efficient (or lazy, if you want to put it that way) and combined both together for easy dinning.
