I've been searching for a bean burger that doesn't fall apart when cooking or mush out the side of my bread. I've finally found it! I used a mixture of pinto and red kidney beans because that's what I had and they were great. I think next time I'll try it with black beans for a little something different. I also added pepper jack cheese and the little amount of effort was well worth the quality and taste of a homemade bean burger. In addition to the amazing cost advantage over pre-made sodium burgers found in the store.
