1/3 cup balsamic vinegar
1tbsp white wine
1tsp Dijon mustard
salt & pepper
Make 2 aluminum foil "boats" and place salmon fillets in center. Mix ingredients and poor over fish. Marinade salmon for about 30 minutes.
Grill salmon (in foil "boats") for about 10 minutes on medium heat. After 10 minutes, transfer fish directly in grill for 5-10 more minutes to finish cooking. (I recommend getting some non stick grill spray to use so the fillets don't stick to the grill - Weber makes a good spray option). Fish should easily flake with a fork when done.
Serve with rice & veggies or over a Caesar salad!
