Put all the ingredients except for the kale in a large crock pot. Cook on high for 4 hours or low for 8 hours until the carrots and cauliflower florets are tender. Adjust salt and pepper to taste.
While the soup is still hot in the crock pot, stir in the kale. It will wilt quickly.
Notes
Turmeric is has an earthy flavor. If you haven't tried it yet, add a little to the soup and add more to taste. You can add up to a tablespoon if you love it!
