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.
