Prepare hollandaise sauce according to package directions; set aside and keep warm.
In a 10-in. nonstick skillet, heat 1-1/2 teaspoons oil over medium-high heat. Whisk the eggs, milk, salt, pepper and garlic powder. Add half of the egg mixture to skillet (mixture should set immediately at edges).
As eggs set, push cooked edges toward the center, letting uncooked portion flow underneath. When the eggs are set, sprinkle 1/2 cup cheese on one side. Layer with 1 cup asparagus, 1 cup crab and 1/2 cup cheese; fold omelet in half. Cover and cook for 1-2 minutes or until the cheese is melted. Invert omelet onto a plate. Repeat for second omelet. Serve with hollandaise sauce. Garnish with chives. Yield: 2-4 servings.
