Directions: Mash the first six ingredients together. Mixture will be slightly dry, so add water as needed until the mixture becomes moistened. Add the onion, tomato, corn and cilantro; mix well. Meanwhile, divide the bean mixture into fourths and form four patties by hand. Heat a medium saucepan over medium-low heat. Spray the saucepan with cooking spray, and cook the patties on each side for 3 to 5 minutes. Resist the urge to flip them or check on them too soon; just let them sit there and cook. Once the burgers are done, slice the avocado into strips and split between the four burgers. Smoosh on a bun, top with condiments of your choice and enjoy! Makes 4 burgers.
