In a large skillet, saute the celery, onion and green pepper in oil until tender. Add garlic; cook 1 minute longer. Add the tomatoes, soup mix, Worcestershire sauce, bay leaf and cayenne. Bring to a boil. Reduce heat; cover and simmer for 15 minutes.
Add shrimp; heat through. Discard bay leaf. Serve with rice. Freeze option: Stir in shrimp but do not heat through. Cool mixture; freeze in freezer containers for up to 3 months. To use, partially thaw in refrigerator overnight. Heat through in a covered saucepan, gently stirring and adding a little water if necessary. Serve with rice.
