Enchilada Sauce (as found on allrecipes.com)

Ingredients:
1 tablespoon vegetable oil
1 cup diced onion
3 tablespoons chopped garlic
1 teaspoon dried oregano
1 teaspoon ground cumin
1/4 teaspoon ground cinnamon
3 tablespoons all-purpose flour
5 tablespoons hot chili powder
4 1/2 cups chicken broth
1/2 (1 ounce) square semisweet chocolate (a couple tablespoons of semi-sweet chocolate chips work just fine!)

Instructions:
Heat oil in a large saucepan over medium-high high heat. Saute onion until tender. Stir in garlic, oregano, cumin and cinnamon; saute for a few minutes.
Stir in flour and chili powder, stirring until sauce thickens. Slowly whisk in chicken broth; reduce until sauce reaches desired consistency. Stir in chocolate until melted and well blended.
