In a large saucepan cook red or green sweet pepper, onion, and garlic in hot oil until vegetables are tender. Stir in flour. Stir in chicken broth, undrained tomatoes, okra, rice, Cajun seasoning, and bay leaf. Bring mixture to boiling; reduce heat.
Cover and simmer for 6 to 10 minutes or until okra is tender. Stir in chicken and crabmeat; heat through. Remove bay leaf. If you like, serve with crackers.
