Thrifty Recipe- Simple Grilled Salmon

It's summer, what a great time to break out the grill. This is a favorite recipe because it involves ingredients we usually have around the house. And the marinating time is only 15-30 minutes so we can make a last-minute decision to have this and the fish is ready by the time the grill is warmed up.
Tip: Make sure to well-oil the grill grate so the salmon doesn't stick to it. Do this by heating up the grill, then using a wire brush to get rid of any old drippings/dirt from the grate. Then, use tongs to rub a paper towel dipped in vegetable oil on the grate several times.

Simple Salmon
From Weber's Big Book of Grilling

Ingredients:
1/4 cup extra virgin olive oil
1/4 cup soy sauce
1/4 cup dijon mustard
3 Tablespoons prepared horseradish
2 Tablespoons brown sugar
1 teaspoon rice vinegar
6 salmon fillets with skin, about 6 oz each and one inch thick (I have made this with fresh salmon from the butcher and with individually frozen salmon filets- thawed of course, both worked great)

1. In a medium bowl, whisk all ingredients except salmon until smooth
2. Place the salmon filets in a large resealable plastic bag and pour in all but 1/3 cup of the marinade. Press the air out of the bag and seal tightly. Turn the bag to distribute the marinade and refridgerate for 15-30 minutes.
3. Remove the filets from the bag and discard marinade. Grill the fillets, skin side down, over indirect high heat until opaque throughout, about 10-12 minutes. During the last 2 minutes of grilling time, brush with the 1/3 cup of reserved marinade. Slide a spatula between the skin and flesh and transfer to serving plates. Serve warm.
