Black beans and raw Limas are not the healthiest but are safe when cooked . Garbonzo, dried Peas and Lentils, Red beans, Mung beans are among the more nutritious choices. I cook some grains with them like Quinoa, Spelt, Barley and chop some dark greens and sweet potato to toss in at the end of cooking then cover and let steam a few minutes before cooling enough to serve. You can freeze and serve later as well.
