I got this recipe from The Zen Monastery Cookbook written by the Monks at the Zen Monastery Practice Center Under the Guidance of Cheri Huber. It's a great recipe and a great book of vegetarian recipes. The soup is very simple, delicious and makes a good side dish, like a tomato soup might. It's totally vegan, but if you are not, you might add farm cheese chunks or a dollop of sour cream.
