I had THE sauce for you until you said "healthy"
But, if you want arguably the best sauce to put on ANY salmon (fish snobs need not apply) here it is:
1 cube butter
2 cloves crushed garlic
1/4 Cup Soy Suace
1/4 Cup Ketchup (Heinz if you're a bleeding heart Democrat)
2 TBS. Yellow Mustard (the crap in the yellow bottle that you put on hot dogs)
Dash of Worcestshire Suace
Melt the butter over medium heat. Once melted, add in the remaining ingredients and cook over low heat for about 5 minutes.
Take your BBQ and get it fired up and hot. Take your fillet-o-king and place it meat side down for approx 3-5 minutes. Get some good grill marks on it, and get it hot/cooked enough so that it doesn't stick to the grill. Flip it over on to it's skin. Baste on the sauce. Take the fish off when it is properly "done". If the middle wasn't close to raw when you took the fish off of the heat, you overcooked and murdered your fish. Remember that fish will "finish" cooking after being removed OFF of the heat source.
Haven't met *anyone* yet who doesn't think this is the cats-meow on salmon.
For the Fish Snobs out there, this is what I'd do for you:
Fillet and skin your fish. Cut in to single and thin portions.
Chop up some basil, cilantro, and other fresh herbs.
In a sauce pan, heat up some olive oil and add in your fresh herbs. Let the herbs infuse in the oil.
Season the fish (salt and pepper).
On a super hot BBQ, take a piece of fish and slather both sides in the olive oil. Slap on the grill. Cook about a minute or so on each side. Serve to whomever is smart enough to have a plate and is standing behind you.
Place the fish on their plate and before they can run away, squeeze a lime wedge over their fish.
Fish Snobs go goo-goo over that.
I can thank Rooster for that one. Damn fine eats right there!

Lastly, take a fillet of salmon and put on some olive oil, cilantro, and salt/pepper. Put it in your Cookshack smoker. Smoke for about 50 minutes at 190 degrees.
More good eats with a nice smokey flavor.
