I have been trying to incorporate more dark leafy green vegetables into our meals lately, not only for health reasons, but for the taste too. Spinach and Swiss chard are standards for me, but lately I've been playing around a lot with the kale family and cavolo nero, a type of dark leafed, loose cabbage. Kale is a bit tough, so I like to blanch it before stir frying it, adding to soups, and so on.

Salads and such are fine in the warm months, but now that it's cold outside here in the northern hemisphere, I tend to prefer cooked vegetables. This homey stewed vegetable dish is rather typical of Japanese 'mom's cooking' - seasonal vegetables all cooked together in a dashi based broth. (I know that green beans are not exactly seasonal, but they are added just for the color; use any green vegetable instead.) It does take a while to assemble and cook, but once you have a big potful it lasts for a few days, so it's a great refrigerator stock dish.

I've tried to use 'ordinary', non-exotic vegetables as much as possible, but I did add a little lotus root since it adds visual flair as well as a nice crunchy texture. This is a one-pot meal due to the addition of potatoes for carbs, and meaty-textured kouya dofu or freeze dried tofu (for which you can substitute extra-firm tofu or even chicken pieces) for protein. You can just pack this into a bento box on its own, or accompany it with rice and pickles.
