  • 1.5 L vegetable stock
  • 210 g red split lentils
  • 1 tsp ground turmeric
  • 1/2 tsp mild chilli powder
  • Freshly ground salt and pepper
  • 1 tbsp coriander chopped


  • Gently heat the oil in a large soup pot and add the diced onion to soften it, stirring occasionally for about 4 – 5 minutes. Then add the diced potatoes and continue to stir for a further 3 – 4 minutes.
  • Add the vegetable stock, lentils, ground turmeric and mild chilli powder.
  • Stir well, bring to the boil and turn down to simmer gently for 20 –25 minutes until all the mixture is completely softened. Remove from the heat.
