Combine marinade ingredients, except lemon slices, in a small saucepan and bring to a boil. Remove from heat and allow to cool to room temperature. Add lemon and pour cooled marinade over fish and marinate refrigerated for 2 to 4 hours. Turn fish occasionally.
To serve: Grill or broil on both sides until just done, approximately 4 to 5 minutes per side. Be careful not to overcook. Salmon should still be translucent in the center. Serve with Soba Noodle Salad on the side.
