Add onion and garlic to drippings in pot; cook until tender, about 8 minutes. Stir in cinnamon and allspice; cook 1 minute. Return meat and sausage to pot. Reserve 1/4 cup of the beef broth.

Heat through.
Whisk flour and reserved 1/4 cup broth in small bowl. Stir into pot. Cook, stirring, until thickened.
To serve, ladle stew into bowls. Top each serving with 2 tablespoons of the cheese. Garnish with cilantro. Accompany with tortilla chips, if desired. Makes 6 servings.
