- To make the patties, place the beans in a large bowl and mash with a potato masher or large fork until mostly broken up with a few bigger pieces. Add the brown rice and mash a bit more, until the rice has broken up.
- Add all the rest of the patty ingredients and mix well. The mixture will seem dry at first but will come together. Form into 4 patties.
- Heat oil in a non-stick pan. Cook the patties for 3-4 minutes on one side, until browned and crispy. Flip the burgers and fry for a further 3-4 minutes.
- Toast the burger buns on a lightly oiled pan. Top with mashed avocado, lettuce, black bean patty, tomato, red onion, mayo/ketchup (if using) and the top of the burger bun. Serve immediately. Enjoy!
