Last-minute marinade

The other day I was looking for a sauce or marinade I could use on grilled salmon, one I could slop on the fish and not have to refrigerate for an hour or two before moving to the grill.  The one I came up with, as best I can recall, was:

• 2 Tbl Dijon
• 3 Tbl soy sauce
• 6 Tbl olive oil
• 1 Tbl minced garlic
• Brush sauce on fish 10 minutes before grilling.

It was better than nothing, but not especially tasty.  The wonderful wife and Katka disagreed; they thought it was excellent.

(I don't know where I found the recipe; I record it here so that maybe I'll be able to find it again some day.)
