Drain black beans and mash in a bowl separately, you could use a potato masher or the back of a fork. Add all of the rest of the ingredients to the beans and mix to combine. Let sit for 20 minutes so the oats can absorb some moisture.
Form into 8 or so medium sized patties. Spray pan with oil and cook burgers on medium heat, 3 minutes per side making sure not to move them too much. Bean burgers are a little more crumbly than regular burgers. Serve with your favorite toppings and enjoy.
For the Sriracha Mayo. Dole out about 1/2 cup or more of Mayo and add 2-3 good squirts of Sriracha to the mayo. Taste as you go and make it as hot or not as you like it. The Sriracha adds an awesome smoky, garlicky heat that is unbeatable!!
