Ingredients:
1 large potato
400g tin red kidney beans,
1 small red onion - finely diced
½ tsp dried chilli flakes
1 tsp ground cumin
1 slice bread blitzed to breadcrumbs
3–4 tbsp vegetable oil
Method
1.Place 1 diced potato in a pan of boiling water and simmer for 12–15 minutes, or until very tender but not breaking apart. Drain well and leave to air dry for a few minutes.
2.In a bowl, mash the rinsed beans using a potato masher. Add the potatoes and mash those too. Mix in the remaining burger ingredients, except the oil. Shape the mixture into four large patties.
3.Heat 2 tablespoons of oil in a large frying pan (preferably non-stick). Cook the burgers over a medium heat for 3–4 minutes on each side until golden, adding a little extra oil when the burgers are turned.
Serve in rolls with salad and salsa.
