DO-AHEAD TIP: Marinate fish for 20 minutes (see recipe).
Prepare marinade: In a medium bowl, whisk together first 8 ingredients
(olive oil through salt and pepper).
Place fish in a large baking dish. Reserve 1/4 cup of marinade then pour remainder over fish. Cover and refrigerate for 20 minutes.
Heat an indoor grill over medium heat. Remove salmon from marinade; grill for 4 minutes per side or until fish flakes easily when tested with a fork.
In a large bowl, toss greens with reserved marinade then arrange on dinner plates; top with fish.
