I know, it's been a while. But I am here to cheer you up hopefully in these rather dire times!
Real Bento: Fresh and Easy Bentos from a Japanese Working Mom is a cookbook by a popular bento blogger in Japan called Kanae Inoue. She takes a very pragmatic, streamlined approach to making bentos, based on her years of making them for her three children for many years - a boy (who is now in college and living away from home) and two girls.
The Just Bento Cookbook 2: Make Ahead, Easy, Healthy Lunches to Go is the sequel to the best-selling The Just Bento Cookbook. It contains almost all new recipes (with the exception of a handful of "classics"), and is designed to expand your bento making repertoire, as well as increase your knowledge of Japanese home cooking in general.
