Use tuna, swordfish, or halibut steaks, cut 1/2" thick. Place fish in
a well-greased wire grill basket. Combine oil, melted butter, and soy
sauce; brush some of the mixture over fish. Grill fish steaks over
medium-hot coals 4 minutes. Turn the wire basket; baste fish again
with the remaining soy mixture. Grill 3 to 5 minutes more or until
fish just flakes with a fork.
