Steam the chopped garlic with the chopped onions in hot oil. Add the diced bread and fry. Fry the sliced mushrooms briefly and deglaze with the white wine.
Pour in the broth and let everything simmer for about 5 minutes. Add the thyme and season with nutmeg, salt and pepper. Mix half of the cheese into the soup.
Put the soup in two plates or soup bowls and sprinkle the rest of the cheese on top.
