1. Add beans to food processor, and until they resemble refried bean consistency. Add cooked rice, bread crumbs, juice or broth, garlic, and herbs and spices. Pulse until these are all very well mixed but still have texture. Or, mash by hand.
2. Heat oil in a pan on medium high heat. Make sure your pan is nice and hot or they may stick. Wet your hands a little with water and form mixture into patties.
3. Fry patties for about 6 minutes on each side. Do not turn until you are certain they are nicely browned. These can only really handle about 1 flip before they start falling apart. You may have to press down a little with you spatula to keep it together. If you break one, no big deal it usually goes back together nicely.
4. Get your buns ready with condiments and such as your burgers are getting nice and browned in the skillet.
Source of recipe: I was so tired of spending $4 a box for a burger substitute so I wrote this recipe upon having leftover rice and beans in the fridge. It turned out so delicious that I make beans and rice just so I can make these burgers later. Also, it's another way to use up bread that is just a little to dry to eat.
