Chop zucchini, green beans, and celery (chop celery into very small pieces to avoid stringy soup). Place in steamer and steam over ~ 4 cups of clean filtered water until very soft – around 15 minutes. Place steamed veggies, steaming water, and parsley, garlic, and watercress into blender and blend until smooth. Sip hot throughout the day.
Ange’s Note: I like to double the batch and make very thick. Then when I want a cup, I fill a mug half full and top up with boiling water. Like instant cup-a-soup! Drink like tea throughout the day.
