Tip the beans and cold mashed potato into a bowl and mash with it together with a fork, potato masher or even your hands!
Add in all the other burger ingredients and mix well.
Heat the oil in a skillet or heavy frying pan. When it is shimmering, carefully slide a couple of the burgers in.
Cook for 4 minutes before carefully turning over. They are more fragile than meat burgers so go gently. Add more oil if necessary.
After 4 minutes on the second side, slide the burgers out and into waiting baps or wraps. Layer up with lettuce, tomato, red onion and ketchup. Yum!
