Avatar: The Last Airbento.

Here's a little something to help take the bad taste out of the mouths of A:tlA fans disgruntled by the upcoming movie treatment: scdsam  has been creating a series of Avatar-themed bentos; Sam's lunchbending demonstrates not only creativity and humor but a knack for nailing character likenesses and expressions using the simplest of materials.

Toph.
Zuko.
Aang. (Not vegetarian; egg--which has some canon defensibility; see "The Great Divide"--and crab proved too useful as sculpting materials.)
Sokka.
Azula.
Katara.

Note that this post will be updated to include any further entries in the series.
