Peel, wash and roughly dice the potatoes. Peel and chop the onion.
Heat the oil. Sauté the potatoes and onions in it. Add soup greens without defrosting, sauté briefly. Add the spinach and pour in 3/4 l water. Bring everything to the boil, stir in the broth and simmer for about 15-20 minutes.
Puree the vegetables in the soup with the cutting stick. Season to taste with salt, pepper and nutmeg.
Cut the ham (remove any fat) into strips. Arrange the soup in preheated soup plates. Place 1 teaspoon of crème fraîche on each. Possibly pull through the soup with a wooden skewer. Sprinkle the ham on top. Wash the herbs and garnish the soup with them.
