This was a great recipe. My only problem with it was that it was very soft when bitten into and pressed. Overall though, the flavor was great and paired well with the guacamole. I would recommend following the recipe as is with spices and such. The only thing I changed was that I added just under 1/4 cup of water to the bean mix before I refrigerated it. I also refrigerated it for 45 minutes and it held together well. As a healthy-but still tasty!- side I baked "fries" in the oven so I had the whole "hamburger and fries" theme in a healthier and more wholesome way. Although it took some work, this is definitely a dish I'd cook again.
