Lentils/split peas are super easy (and less flatulent!). 1 part lentils, 3-4 parts water or vegetable broth, simmer for 15-30 minutes (less for red lentils, more for split peas). Season to taste with salt/pepper, hot sauce, curry, or whatever else. Or saute up some onions and/or mushrooms in the pot first and then toss in the lentils and broth. Or shred in some kale/swisschard/cabbage/lettuce and eat beans & greens.
