In a bowl coat chicken pieces with a mixture of flour, coriander, cumin, paprika, salt, and cinnamon. Set aside.
In a 4-quart Dutch oven cook onion and garlic in hot oil about 5 minutes or until tender. Remove from Dutch oven, reserving oil in pan. Add chicken pieces, about half at a time, to pan. Cook quickly until lightly browned, stirring frequently. Return all chicken and the onion mixture to pan. Add crushed tomatoes, beans, water, raisins, and olives. Bring to boiling; reduce heat. Simmer, covered, about 10 minutes or until chicken is tender, stirring occasionally. Spoon couscous into soup bowls. Ladle stew over the couscous and sprinkle with snipped cilantro. Makes 6 servings.
