This girl posts a new recipe on Bento TV (a video blog) everyday (link:
http://www.bentotv.com/). I have spent some time watching this with a mixture of fascination and disbelief (the disbelief stems from the fact that her lunches are tiny). As
Starwood Lurker mentioned earlier, it is very similar to an Indian "tiffin". A good idea if you can keep all the pieces together.
