Cut the onion and garlic into cubes and sauté in butter. In the meantime, cut the potatoes and zucchini into cubes, add and sauté briefly. Add the vegetable stock and simmer everything until soft (approx. 10 min). Shortly before the end of the cooking time, add the wild garlic cut into strips, reserve something for garnish if necessary. Add the cream cheese and, if you like, some cream and puree the soup finely. Season to taste with salt and pepper.
