I'm starting to get a better sense of the bento and able to incorporate the color green (which was sorely lacking in the first few), and finding a good balance of protein, whole grain carb, and fruit/vegetables. This is one I put together for Ken in his 'new' box directly from Japan.
Spicy grilled chicken on a bed of lettuce
sunflower seeds
whole grain crackers
sharp cheddar cheese
blueberries
peanuts
