See our on-line video, Cooking Dried Beans, for tips on cooking perfect beans!
Use a Blender
If you don't have a food processor, blend cooked peppers, onions, cumin and salt with an electric blender instead. Transfer to a large bowl. Add the beans and rice; mash together with a potato masher. Stir in walnuts and egg, then continue as directed.
Mix rice mixture and shape into cakes as directed. Wrap tightly and freeze up to 1 month. Thaw in refrigerator before cooking as directed.
