4 (3/4-inch thick) tuna steaks
1 cup commercial Italian salad dressing
2 teaspoons freshly-ground pepper
1 lemon, quartered

Place tuna steaks in a 12 x 8-inch dish; pour salad dressing over tuna. Cover and refrigerate 1 hour, turning once. Remove steaks from marinade; reserve marinade. Sprinkle pepper on both sides of steaks.

Grill, covered, over medium coals (425 degrees F) for 5 minutes on each side or until fish flakes easily when tested with a fork, basting occasionally with marinade.

Place on a serving plate; squeeze a lemon wedge over each steak.
