Sweet Potatoes Topped with Black Bean Chili

Chili makes a good topping for vitamin-rich sweet potatoes. The black beans look great on the bright orange sweet potatoes, and the taste is right. The trick of using chipotle chilies to add flavor to a meatless chili was devised by cookbook author Deborah Madison when she was the chef at Greens, the vegetarian restaurant run by the San Francisco Zen Center. It has since been widely copied.
