Red kidney bean and carrot veggie burgers

In my fridge I had leftover (white) rice and a carrot that both needed to be used up. The rice reminded me of the PPK beetroot burgers I’d made recently, which used beetroot, lentils and brown rice, held together by almond butter. So I substituted grated carrots, red kidney beans and the white rice, and (for fun) I used peanut butter to bind them together. I was so pleased with myself for having invented a veggie burger (ahem, I mean for adapting an existing and most excellent recipe).
