New Invention: The Sushi Bun!

I have created the world's first Sushi in a Bun!   What madness led to this!?

spam, egg, cucumber, imitation crab sushi with eel sauce

Well, I've been practicing making red-bean paste buns, and had run out of red-bean paste with one more dough skin left to spare.  "What shall I fill this bun with?" i asked.  Having just consumed a sushi dinner (also made by yours truly) my friend cried out, "SUSHI!"  

Looking good & ready for steaming!

One of these buns doesn't look like the others!

ah! suspicion was correct!  yum!

Would i do it again?
probably not except for the surprise factor, which is hilarious. It would be better if it didn't have any rice, since it's repetitive with the bread of the bun. So just a seaweed wrap of the meat and veggies in a bun would be great.

A fricken' sweet cookie, literally.

While we're at it, reminds me of another food-in-food i saw posted recently Living in a Gamers Paradise from PAX East.  In this case, the cookie-in-cookie works because the crunchy texture of the oreo is different than the soft, chewy cookie around it, so it adds to the composition.  And inside the oreo is sweet cream.  My sushi-in-bun doesn't work as well because the rice texture is too similar to the bread.

Hmm i think this food-in-food idea will have to be explored further, can you think if any interesting combinations?   Comments welcome!
