Heat olive oil in a large nonstick skillet over medium-high heat. Sprinkle chicken with 1/4 teaspoon black pepper and 1/4 teaspoon salt. Add chicken to pan; cook 10 minutes, browning on all sides. Remove chicken from pan; reduce heat to medium.
Add 1/2 teaspoon black pepper, onion, and the next 8 ingredients (onion through bay leaf); cook 5 minutes, stirring occasionally. Add broth; bring to a boil. Return chicken to pan, and reduce heat. Simmer, uncovered, for 15 minutes or until chicken is done. Discard cinnamon and bay leaf.
While chicken cooks, place olives in a small saucepan; cover with water. Bring to a boil; drain. Repeat procedure. Add olives and juice to chicken mixture; sprinkle with cilantro. Serve over couscous.
