This soup has existed about as long as farming has in western civilizations. It is the mainstay peasant soup of France and can be used as the foundation for any number of other vegetable soups. In restaurants this soup is nearly always pureed, but in the old-fashioned country version it is not — the vegetables are simply cooked to near disintegration. My version is a compromise because it is intended as a main dish and somehow a pureed soup never seems to make it — the hungry mouth needs something to chew on, I guess,
Serves four.
