Add brown rice to a small pot with 1 cup water and bring to a boil. Reduce to low heat to maintain a simmer and cook for about 30 minutes (time may vary depending on strain of rice). While the rice cooks, prepare the remaining ingredients.
In a food processor (or high powered blender) add oats and cashews and blend until mixture resembles course sand. Transfer to a bowl.
Next, roughly chop onion and garlic and add to the food processor. Process into small pieces but not a mush. Add to frying pan with a dash of water. Process mushrooms as well.
Once the mushrooms are ready, you can start to fry your onion and garlic. Pan fry on medium heat until translucent. Then add mushrooms and fry another 3 minutes, until mushrooms are cooked. Put aside to cool.
Next, process black beans and rice. Put aside.
In onion and mushroom mixture, add all the spices, soy sauce, tomato sauce, and liquid smoke. Mix well.
Add all ingredients (oats, cashews, black beans, rice, panko) to the mushroom mixture and stir well until everything is well combined.
Use your hands to shape the mixture into palm sized patties. This recipe should produce about 12 burgers.
Pan fry over medium/low heat with a lid until browned or wrap in plastic wrap and freeze for later enjoyment.
