You can make these burgers as big or as little as you want - slider size are perfect as appetizers and larger burgers make great mains. You really only need to cook these through to cook the raw flour. If they start to burn on one side, turn down the heat slightly.
Combine beans, sweet potato, almond butter, red onion, ginger, garlic, flour, and soy sauce. Mix well until combined.
Preheat a non stick skillet over medium heat and spray with cooking spray. Shape bean mixture into hockey puck size patties and place in pan, flattening down if necessary.
Cook about 3-5 minutes per side, or until golden brown. Remove and from pan and continue cooking the remainder of the patties. (it may take you 2-3 batches).
