If you have two small wire racks, you can easily cook a fish (and impress your friends) on your outdoor grill. First, find toaster-oven or cooling wracks and some fireproof wire. Oil the racks, then put the fish between the them and tie the racks together. Grill the fish on one side, then flip your newly constructed basket with large tongs or a spatula. This makeshift cage will keep delicate fish from breaking apart.
