About 16 years ago when I was still back in the UK, I had some of my Japanese exchange student friends around my gaff. I didn't have any food to feed them at the time and all that was available was plain rice ^^;
Kenichi says to me "Jyubun dayo!" meaning "thats more than enough!" He then whips out some sachets of power looking substance which he then started to sprinkle over the rice.
I was puzzled as to how powder could turn white rice into a meal for three.
That was my first encounter with Furikake pronounced "furi-karkeh." Furikake is basically dried food like eggs, fish, squid, seaweed etc. This powdery mix of dried food on rice alone is enough to fill you up without any extra dishes.
