Various school lunches from around the world. School lunch doesn't really represent the best a country has to offer, but we still love it, because we grew up on it.
Just as a note, bento refers not only to the container and separated items in the lunch, but also to the style of packing and (often, though not always) proportion of starch to vegetable to protein. When packed in the standard manner a particular sized box will roughly correspond to the number of calories in the meal. For a more traditional look at bento you may want to check out JustBento.com
