Mash the beans with a fork or a potato masher.
Add the carrot, onion, potato, corn, spring onion and salt and pepper and mix until well combined.
Shape the mixture into 6 patties.
Heat about two tablespoons of oil and cook each patty until done, about 3 minutes on each side.
Serve on buns with your favourite burger ingredients like lettuce, tomato, and beetroot.
