Sweet potato and almond butter burger

1 Boil a kettle, pour the water into a saucepan and carefully add the kumara. Cook for 8 minutes until tender. Drain well.

2 Heat the oven to 200°C/180°C fan. Put all of the ingredients except the oil and flour into a food processor and season well. Pulse a few times until the mixture has blended but still retains some texture.

3 Tip the mixture onto a clean work surface and divide into four portions. Then, dust your hands with flour before shaping each portion into burger-shaped patties. Set aside on a flour-dusted plate.

4 Pour the oil into a large frying pan over a medium heat and cook the burgers for 8 minutes on each side until well browned. Serve in burger buns with lettuce, roasted peppers, hot sauce and extra almond butter.
