  1. On he bottom of large pot sauté leeks on half of the oil or butter till soft.
  2. Then add the rest of the oil or butter, mushrooms and potatoes, sauté for another 5 minutes.
  3. In meantime dissolve cubes in hot water to create broth.
  4. Add the broth to the pot with leeks and mushrooms, cover and cook on medium fire for about 20 minutes.
  5. Remove from fire, add spinach and stir well.
  6. Mash some of the potatoes for the soup to look creamy, season with salt and freshly ground pepper and serve to the plates.

Skip the potatoes, add a bit of crème fraîche to make the soup creamy and serve with freshly baked bread sticks as like to do sometimes.
