This turned out to be a most delicious soup...better than I had expected given the simple ingredients. The recipe comes from a new cook book by Crescent Dragonwagon "Bean by Bean". You begin by mixing together finely chopped garlic and butter.
Chop a whole red onion.
Saute the onions and celery in a large pot.
Add potatoes, fresh green beans, and vegetable stock.
Cook until bean and potatoes are tender. Puree the soup in a blender or a hand held mixer.
Add a dollop of the garlic butter and freshly cracked pepper. It was delicious and nutritious!
