Super, Super Yummy Emerald Soup

1. In a large pot, combine stock, broccoli, celery, cucumber, and scallions. Cook until broccoli is soft, about 20 minutes.
2. Add parsley, spinach, and watercress. Cook for an additional 3 minutes.
3. In batches, blend ingredients in a blender and return to pot. You can reheat it if needed, but it will remain pretty hot through the blending stage.
You don't need any seasoning! Its amazing!
