Add cold water to the lentils, boil and simmer for about 30-40 minutes at low heat (in the Kelomat it is ready in about 8 minutes).
In the meantime, briefly sauté carrots, celery, potatoes and leeks in oil, each diced and cut into rings or slices, then add vegetable soup. Cover and cook at low temperature for 5-8 minutes until al dente. Then mix lentils and vegetables and season with sea salt, white pepper and sprinkle with finely chopped celery greens and parsley.
Add.
