Squeeze 1 teaspoon (5 mL) juice from 1 lemon half. Slice remaining half and set aside.
Preheat oven to 425`F (220 C). Combine crab, Hellmann's® Real Mayonnaise and Parmesan cheese in small bowl; set aside. Melt margarine in microwave-safe bowl; whisk in crumbled Knorr® Vegetable Bouillon Cube until dissolved.
