Add the celery, carrot, onion, zucchini and garlic to a pan over medium heat along with the turmeric and salt. Saute until fragrant, approximately 5 minutes. Pour in the 6 cups of water, and bring to a roaring boil. Lower the heat, and simmer, uncovered, for approximately 10 minutes.
When safe to handle, using an immersion blender or countertop blender, combine the soup until a velvety smooth broth is formed. You can add more water as needed to thin to a desired consistency and sprinkle in fresh parsley for color.
Use this as a nutrient dense broth of soups, to cook your rice in or for sautéing vegetables.
