Place fish fillet skin side down on a sheet of aluminum foil. Brush or pour French dressing over the center of the fillet (along lateral line), then cover the fillet with aluminum foil. On a
barbecue grill over low - medium flames, the fish will bake and the dressing will work it's way into the meat. Fish is done when it flakes easily.
Other Notes
This is a really simple, flavorful way to cook trout, especially for shore lunches. You can also use Ranch dressing instead of French.
