This is pictured with baby spinach instead of watercress, as apparently it is still out of season in Michigan so I couldn't get it. I got this recipe from a healthy cooking cook book that someone gave me back in the early 90's. I can't remember the name of the book, but I sure wish I could. I used it a lot. It had some really nice recipes in it. If you know this recipe from a cook book that came out in the early 90's, send me a message! Anyway, this soup is really great when you want a simple dish to add a bit more veg. to your meal. It also makes a nice starter for Asian themed meals. Enjoy!
