I just wanted to drop a little note that I saw justbento.com name checked in a post on Serious Eats. (I'll post below) Where else have you seen the site mentioned in a casual way?
In the colder months, I like to make a pot of turkey chili or cassoulet or curry or daikon beef stew or some other healthy, filling entree and some haiga or brown rice, along with pears, grapes, citrus or whatever produce is in season.
In the warmer months I like simple but interesting sandwiches on toasted nice bread or maybe a light protein and cucumber salad or similar.
I also like to stroll over to www.justbento.com 
But I am half Japanese, so that is my excuse.
By the way, I have been known to pack chopsticks in my lunch!
