snacks while flying?

[OakLeaf]

On a flight from Malaysia to Japan recently, they served onigiri, a rice ball (except it's a packaged triangle), and it was perfect, just filling enough, tasty, and reasonably healthy (compared with chips and stuff). But I wouldn't know how to make my own or find them in the US.

Oh, that sounds good! Is it just a ball of sushi rice? That's easy enough. We just started getting brown sweet rice in the local stores, too. It works fine for maki, but I'm not sure whether it would hold together quite well enough for nigiri. I haven't even mastered white rice nigiri... but if all I have to do is squeeze it together and jam it in a ziploc bag, then the only challenge is convincing security it's not a "gel"
