Puree a can of beans, freeze the puree, and use these magical frozen bean cubes in anything you can think of. Add one to your bowl of oatmeal, throw a few in the blender when whipping up your kale smoothie, or Leslie suggested mixing them into pasta sauce, soups, or cooked whole grains. One cube is 26 calories, and offers 1.3 grams of fibre and 1.6 grams of protein, but won't affect the taste of the dish.
