Toast bread cubes in butter until crisp.
Fry the bacon in a saucepan. Sauté garlic and the light parts of the spring onions in it. Pour in wine and stock, simmer for six minutes. Season with salt and pepper.
Pour soup into a deep dish and serve with sour whipped cream, croutons and the remaining spring onions.
Note: the mass liquid is too little. Supplement with vegetable soup or similar!
Our tip: use a bacon with a strong flavor – so you give this dish a special touch!
