4 fish steaks (halibut, salmon, or swordfish), about 3/4 inch thick
1/4 cup Kikkoman soy sauce
3 Tbsp. minced onion
1 Tbsp. chopped fresh ginger root
1 Tbsp. sesame seed, toasted
1/2 tsp. sugar substitute

Place fish in a single layer in a shallow baking pan. Measure soy sauce, onion, ginger, sesame seed and sugar into blender container; process on low speed 30 seconds, scraping sides down once. Pour sauce over fish; turn over to coat both sides. Marinate 30 minutes, turning fish over occasionally. Remove fish and broil or grill 4 inches from heat 5 minutes each side, or until fish flakes easily when tested with a fork.
