You can make this recipe using your slow cooker on either the low or high setting. This recipe will cook quickly on high so be ready to come back to it after 3 hours. It will take about 6 ½ hours on low. During the last 30 to 60 minutes of cooking you can add diced yams, chopped kale, chopped carrots, or any other vegetable you have that needs to be used. If your digestion is weak, I suggest soaking the beans and rice overnight in filtered water, then rinsing and draining in the morning.
