Meanwhile, prepare lemon dressing: in jar with tight-fitting lid, combine oil, lemon juice, mustard, salt, and pepper. Refrigerate halibut until cold.

4. In medium-size bowl, combine potatoes, beans, and 2 T lemon dressing; toss until well combined.

5. To serve, line serving platter with lettuce leaves and spoon potatoes and beans onto lettuce toward rim. Flake halibut and place in center of potatoes and beans. Sprinkle halibut with caviar, if desired, and garnish with crab. Drizzle remaining dressing over halibut and serve.
