I think I found this recipe as part of Bon Appetit's Top 10 Vegetarian Recipes of 2010. And boy, were they right! It is delicious!
Vegetarian Black Bean Chili with Orange and Cumin
2 oranges (juiced) (or 8 ounces orange juice)
2 T. olive oil
2 C. chopped onions
4 garlic cloves, pressed
4 t. chili powder
4 t. ground cumin
2 t. ground cinnamon
3 15.5-oz cans seasoned black beans, drained

Hot pepper sauce
Sour cream or plain yogurt

Grate enough orange peel to measure 1 1/2 teaspoons. Juice oranges. Heat oil in heavy large saucepan over medium-high heat. Add onions; sauté 5 minutes. Mix in garlic and spices. Add beans, tomatoes, and half of orange juice (1/2 cup). Simmer over medium heat until heated through and flavors blend, stirring often, about 15 minutes. Mix in orange peel and remaining orange juice (1/2 cup). Season to taste with hot sauce, salt, and pepper. Ladle chili into bowls. Top with sour cream and cilantro. Pass extra hot sauce alongside.
