Step 1

Heat a large saucepan and dry-fry 2 tsp cumin seeds and a large pinch of chilli flakes for 1 min, or until they start to jump around the pan and release their aromas.

Step 2

Add 1 tbsp olive oil and 1 chopped red onion, and cook for 5 mins.

Step 3

Stir in 140g red split lentils, 850ml vegetable stock or water and a 400g can tomatoes, then bring to the boil. Simmer for 15 mins until the lentils have softened.

Step 4

Whizz the soup with a stick blender or in a food processor until it is a rough purée, pour back into the pan and add a 200g can drained and rinsed chickpeas.

Step 5

Heat gently, season well and stir in a small bunch of chopped coriander, reserving a few leaves to serve. Finish with 4 tbsp 0% Greek yogurt and extra coriander leaves.
