Place fish in a shallow glass baking dish. Mix remaining ingredients together in a small bowl. Add marinade, turn fish once to coat. Cover and refrigerate at least 1 hour but no longer than 24 hours, turning occasionally. Spray grill rack with nonstick cooking spray. Grill fish 4 inches from heat over a medium heat for 7-10 minutes per side or until fish flakes easily with a fork. Frequently brush with remaining marinade while cooking.
