Grilling fish is a great way to add flavor to fish meat. If you like a more delicate flavor, pack the fish in foil, add wine, lemon juice, some vegetables and herbs. The fish will be as flavorful, but has no grill marks. It is very moist. Good news is, you don't have to clean the grill afterwards.
Place 2 pieces of aluminum foil on a flat surface, large enough to fold over the fish and seal. Use 2 layers for normal aluminum foil or 1 layer for heavy duty foil.
Place each salmon fillet, skin down on the foil. Sprinkle fish with salt and pepper.
Cut tomatoes in 8 pieces. slice onion thinly and divide over foil.
Mix white wine, lemon juice, mustard, and capers and pour on fish.
Fold aluminum foil around the fish and seal closed.
Place each foil packet directly on the grill of medium-high heat.
Cook/grill for approx. 10 minutes.
Open packets and garnish with parsley. Serve in foil and enjoy.
