Baked Salmon with Creamy Onion Sauce

Preheat oven to 400°.

Line a jelly roll pan with nonstick foil. Arrange fillets, skin sides down, on foil; sprinkle with pepper and 1/8 teaspoon salt.

Bake at 400° for 12 minutes or until fish flakes easily when tested with a fork.

While fish bakes, process yogurt and next 4 ingredients in a blender until smooth.

Place fillets on a serving platter. Serve with sauce and lemon wedges.
