Arrange eggs in single layer in large saucepan. Add enough tap water to cover eggs by about 1 inch. Cover and quickly bring to a full rolling boil; turn off heat. Remove pan from burner to prevent further boiling. Let eggs stand covered in hot water for 15 minutes. Drain; immediately place in ice water until cooled (about 10 minutes). Crack eggs by tapping them gently all over. Roll eggs between hands to loosen shell; peel, starting at large end. Hold under running cold water to help remove shell. Cut eggs in half lengthwise, scoop yolks a medium bowl. Mash yolks with a fork or pastry blender until fine. Stir in mayonnaise, mustard, salt and cayenne pepper. To Bourbon Street Chicken Salad, add 1 tablespoon egg yolk mixture. To Shrimp and Crab Salad, add 2 tablespoons egg yolk mixture. Spoon each mixture into 8 egg halves. Spoon remaining egg yolk mixture into pastry bag fitted with a star tip and pipe into 8 halves; garnish each with a small sliver of sundried tomato. Use remaining egg mixture to pipe a small rosette on top of chicken and shrimp stuffed eggs; top with a small parsley leaf, dill sprig or caper.
