Serve over rice for a burrito bowl or with tortillas as tacos. Chipotle chiles add a huge amount of flavor to this dish. They come in a four ounce can packed in sauce. Freeze remaining chiles and sauce to use at another time. You can use a pressure cooker, slow cooker (6 hours on high or 9 hours on low) or oven (325 degrees for 4 hours and use 3 cups broth).
