1. Heat a large nonstick skillet over medium-high heat. Coat pan with cooking spray. Add tomato; cook 1 minute or until thoroughly heated. Combine cooked tomato, olives, parsley, and 3/4 teaspoon oregano in a small bowl; keep warm.

2. Wipe pan dry with a paper towel; return pan to medium-high heat. Recoat pan with cooking spray. Sprinkle fillets evenly with 3/4 teaspoon oregano, salt, and pepper. Add fillets to pan; cook 3 minutes on each side or until fish flakes easily when tested with a fork or until desired degree of doneness. Squeeze 1 lemon wedge over each fillet; drizzle each evenly with oil. Top evenly with olive salsa.
