Chilli beanburgers

We often end up having burger-based meals, just out of convenience, so today I thought I'd have a(nother) go at making my own - mainly for variety but also because I feel that they are healthier because I can monitor what goes in them. So here goes:

Half a mug of white rice, boiled in a lot of water for half an hour or so.
1 standard tin red kidney beans
2 small onions, chopped finely
Half a red pepper, chopped finely
2 teaspoons potato flour - probably optional but I think it helps a lot with the binding.
1 teaspoon paprika
1/2 a teaspoon each of cayenne pepper and cumin

Saute the onions and pepper in a small sunflower oil until they soften.
Mix the rice, beans and spices together and mash with the potato masher. (all high-tech around here!)
Stir the pepper and onions in, make sure it is thoroughly mixed.
Leave it all to cool (unless you'd already left the rice for a bit!) then shape into six patties. Bake for 30-40 minutes, turning at least once.

I like this recipe because it uses cheap, basic ingredients that can be bought and stored easily. (At a pinch the onions and peppers could be left out, but they do make it a lot nicer) It does involve a lot more prep than whipping store-bought burgers from freezer to oven, but the beauty of it is you can make extra burgers to freeze for another time.
