This is the original, from-scratch recipe from Kit Carson's granddaughter, as given to Sam Arnold, original owner of the Fort Restaurant in Denver, Colorado. Adapted from Time-Life Foods of the World. Although there are many versions using cooked chicken and prepared broth, the original uses raw turkey legs and cooks them in seasoned water to make a savory soup. The avocado slices are Arnold's addition, so I have made them optional. If using frozen turkey, defrost thoroughly before cooking. Prep time includes time to soak the chickpeas (garbanzos).
Carson City, the capital of Nevada, is named in Kit Carson's honor.
