Keto Shiitake Soup of the Sea

This soup is keto friendly and full of fiber. I love the flavors of the sea and the deep flavor of re-constituted, dried shiitake mushrooms. It adds a depth of flavor to this Asian sour and salty broth. I use anchovies as an alternative to the fish sauce in my Asian-inspired recipes because the fish sauce has just too much of an unknown list of ingredients for my liking.
