Peel and finely dice the onions and garlic. Wash, drain and clean the salad and chop it finely, except for something to garnish. Heat butter in a pot. Add onions and garlic and fry.
Add the salad and let it collapse. Deglaze with white wine and stock. Bring to the boil and simmer for about 3 minutes.
Peel, wash and finely grate the potatoes. Add cream and potato to the soup, bring to the boil and puree finely, season with salt and pepper. Clean and chop the mushrooms. Heat oil in a pan.
Fry the mushrooms for about 6 minutes while turning, season with salt and pepper. Arrange the soup in bowls. Spread mushrooms and remaining salad on top. Sprinkle with pink pepper. Baguette tastes good with it.
