Cooking Instructions
- Preheat the oven to 200C / fan 180C / gas mark 6. Cut the sweet potato into thin fries (peel optional). Transfer to a baking tray and toss with half the paprika, 1/2 tbsp oil and a pinch of black pepper. Bake for 20-25 mins, until golden, turning halfway.
- Thinly slice half the onion, and finely dice the remaining. Heat a frying pan with 1/2 tbsp oil on medium heat. Add the sliced onion and cook for 4-5 mins, until softened. Season with sea salt and black pepper then transfer to a bowl. Keep warm.
- Make the burgers; add the diced onion to the pan and cook for 2 mins. Drain and rinse the beans, then add to the pan along with the chilli flakes (to taste), cumin and remaining paprika. Cook for 3-4 mins, then add 4 tbsp water (2 tbsp for 1 person). Cook for 1 min, then transfer to a bowl with the flour.
- Mash the bean mixture into a chunky consistency and leave to cool. Then, with wet hands, shape the mix into 2 burgers. Wipe the pan and reheat with 1 tbsp oil on medium heat. Add the burgers and cook for 3-4 mins, on each side, until golden.
- Make the guacamole. Dice the tomatoes. Roughly chop the coriander. Quarter the lime. Roughly mash the avocado with the back of a fork and place it into a small bowl. Add the tomatoes, coriander and juice from 2 lime wedges. Season with sea salt and black pepper and mix
- Serve the burgers topped with fried onions, fries and guacamole on the side. Garnish with the remaining lime wedges.
