It's funny I did have sushi for breakfast. There is a great Japanese market nearby (Mitsuwa) and I ran over there a couple of days ago and loaded up on sushi and kinpira (seasoned burdock root).

There are all kinds of sushi. Personally not certain if I could do something like a tuna roll for breakfast but my sushi tastes tend to run to the classics like - Inari and Futomaki. Futomaki, a very "old fashioned before sushi bars" sushi is made with nari, sushi rice, egg, burdock, spinach, ginger and either eel or crab. Not much different then a gourmet omelet. Inari is just fried and seasoned tofu stuffed with sushi rice. YUM!!!!
