Preheat the oven to 180 ° C fan oven or 200 ° C top / bottom heat.
Crush kidney and cannellini beans with a fork. Add all other ingredients and mix well. Then shape into 8 large or 16 small burgers with wet hands.
Now turn the burgers in the additional breadcrumbs and then spray or brush with olive or sunflower oil 1-2 times on each side and place on a baking sheet lined with baking paper. Bake in the oven for about 25-30 minutes, then turn and brown the other side under the grill for about 3-5 minutes. Keep an eye out!
Tastes best in a burger bun with salad and homemade fries. I always do this with spray oil in the oven, because it is so easy to dose and it therefore remains lower in calories.
