step 1 Heat the stock in a large pan and add the lentils.
step 2Bring to the boil and allow the lentils to soften for a few minutes.
step 3Add the carrots and leeks, and season (don’t add salt if you use ham stock as it will make it too salty). Bring to the boil, then reduce the heat, cover and simmer for 45 mins-1 hr until the lentils have broken down.
step 4Scatter over the parsley and serve with buttered bread, if you like.
