Place carrot into a bowl, and fill with a little water. Cover with plastic film, and cook in the microwave for 2 minutes or until soft. Drain.
Mash beans and steamed carrot in a large bowl. Mix in green pepper, onion, salsa, breadcrumbs and wholemeal flour. Season with salt, black pepper and chilli powder. Add more flour to create a firmer mixture, or more salsa if the mixture is too stiff. Form mixture into 8 patties.
Heat a large frying pan over medium high heat, and add olive oil. Fry the patties for about 8 minutes on each side, or until browned and firm.
Really love these burgers, I use a food processor instead of mashing, much easier. I also make double the amount and use a can of 5 bean mix as well as the can of kidney beans. To give a bit of crunch I add sunflower seeds and sesame seeds - 07 Apr 2014
