One-pot beans, greens, and grains

I ran into this in the New York Times food section and it’s so stupid easy, I can’t believe this sort of thing hasn’t crossed my radar before. Basically it’s this: cook any grain. When it’s almost done, dump on any kind of chopped greens and any kind of cooked (canned) beans and finish cooking. Season at will. I went sort of Mexican tonight with rice, kale, and pinto beans seasoned with onions, garlic, and chili powder. It’s good, it’s cheap, it’s nutritious, and it’s vegan. The only downside I can see is that I’m going to be eating this for a week because it makes a lot.
