Black Bean and Sweet Potato Chili

This is a great gateway recipe into vegetarianism - it is easy to make, has the great flavors of a traditional chili, and made with veggies & beans most people like.  What puts this one over the top though, is the garnishes... don't skimp on the orange zest, avocados, or crunchy tortilla chips!  Super duper tasty.  http://www.myrecipes.com/recipe/sweet-potato-bean-chili
