In a large skillet over medium-high heat, cook beef, onions, pepper and celery 7-8 minutes or until no longer pink, breaking into crumbles. Add garlic; cook 1 minute longer. Drain and transfer meat mixture to a 4- or 5-qt. slow cooker. Add next eight ingredients.
Cook, covered, on low until rice and vegetables are tender, 4-5 hours, stirring once. Top with olives and cheese before serving.
