The rice takes the longest to cook, so start by boiling water and cooking your rice.
Next, dice the onion and garlic and add them to a sautee pan with hot olive oil. Cook for a few minutes before adding the diced red pepper and mushrooms. Cook for about 10 minutes or until the peppers are soft.
Add cooked vegetables to a blender and blend until it is mostly smooth, but not completely. I used an immersion blender.
Next, add the red kidney beans and give it a quick blend. You want the beans to be chopped into smaller pieces but not blended all the way to a smooth consistency.
Stir in the rice and spices. Then add in the oat flour, 1/4 c at a time. You may not need all of the oat flour, but keep adding until it is a consistency that will stick well together.
Once you have a good consistency, make the dough into patties. I had enough dough for seven patties. Let sit in the fridge for about 30 minutes (this will help keep them in tact).
When you are ready to eat them, pan fry them with olive oil, about 2 minutes on each side. You should get a nice brown color, it should almost look charred.
