Add fish to pan; sauté 5 minutes on each side or until fish flakes easily when tested with a fork or until desired degree of doneness. Remove fish from pan; cover and keep warm.
Recoat pan with cooking spray; add nuts and garlic to pan. Sauté for 30 seconds. Add 2 tablespoons raisins, orange juice, kalamata olives, and bell pepper to pan; cook 1 minute or until liquid evaporates. Serve with fish.
