Heat a large nonstick skillet over medium-high heat. Coat pan with cooking spray. Sprinkle fish evenly with 1/4 teaspoon salt and 1/4 teaspoon pepper. Add 2 fillets to pan; cook 4 minutes on each side or until fish flakes easily when tested with a fork or until desired degree of doneness. Remove from pan; keep warm. Repeat procedure with remaining fillets.
Add white wine to pan; cook 30 seconds or until liquid almost evaporates. Combine shallots and remaining ingredients, stirring well with a whisk; stir in remaining 1/4 teaspoon salt and remaining 1/4 teaspoon pepper. Add shallot mixture to pan; sauté 1 minute or until thoroughly heated, stirring frequently. Place 1 fillet on each of 4 plates; top each serving with about 3 tablespoons sauce.
