The protein cooking time listed in this recipe has been updated.

As of December 2025, we’ve revised cooking times for all our proteins to reflect improved food safety guidance.

Check out the latest recommended times in our Cooking Guidelines.

  1. Coarsely grate the sweet potato (peel optional). Finely chop or grate the ginger. Finely dice the chilli (remove the seeds for less heat), onion and tomatoes. Halve the lime. Make the salsa; in a small bowl, mix together the tomatoes, half the onion, juice from half the lime, a pinch of sea salt and black pepper.
  2. Heat a large frying pan with 1 tsp oil on medium heat. Add the coriander, ginger, sweet potato, half the chilli (to taste) and the remaining onion. Cook for 5 mins, until softened.
  3. Transfer the sweet potato mixture to a bowl and mix with the flour and a pinch of black pepper. Leave to cool for 5 mins, then form into 6 round rösti patties, around 1cm thick. Reheat the pan with 1 tbsp oil on medium-high heat. Add the röstis and cook for 3-4 mins, per side, until golden brown.
  4. Bring a saucepan filled with salted hot water to a boil. Add the green beans and boil for 2-3 mins, until cooked. Drain, then season with sea salt and black pepper.
  5. Roughly mash the avocado with the back of a fork. Season with black pepper and a squeeze of lime juice.
  6. Serve the röstis with avocado, salsa and green beans. Drizzle over the yoghurt and squeeze over the remaining lime juice. Sprinkle with nigella seeds and chilli (to taste).
