1. Heat a nonstick skillet over medium-high heat. Sprinkle fish with 1/2 teaspoon pepper and 1/4 teaspoon salt. Place fish in lightly sprayed pan; cook 4 minutes on each side or until fish flakes when tested with a fork or until desired degree of doneness. Remove fish from pan; let stand 3 minutes.
2. While fish cooks, combine remaining 1/2 teaspoon pepper, remaining 1/4 teaspoon salt, tomato, and remaining ingredients, tossing well. Serve salad with fish.
