Green Chile, Tomato, and Potato Soup

From New Mexico Magazine. Add a pound of ground lamb or beef if you like. The "chili powder" should read chile, not chili, but the software keeps changing the spelling of the ingredient on me. It should be pure ground red chile, not chili powder, which has other ingredients added to it.
