This is from Allrecipes.com, and it was delicious.
This recipe is simple – season your salmon with garlic powder and lemon pepper, then marinate the salmon in a four part, easy to make in almost any kitchen marinade:
1/3 cup soy sauce
1/3 cup brown sugar
1/4 cup vegetable oil
1/3 cup water
Mix those ingredients until the sugar dissolves (which happens really quickly due to the soy sauce), then place the salmon in the marinade for 2+ hours. I marinated two salmon filets for about five hours.
Cook on medium-high on a pre-heated grill for approximately 6 minutes per side. The flavor is mildly sweet, not overpowering at all.
I served baked potatoes with chive-sour cream and shredded cheddar, starting with a light salad with garlic-ginger wontons.
