In a medium bowl, combine chopped lobster meat, mayonnaise, lemon juice, chives, and Dijon mustard.
Season with salt and pepper to taste, mixing gently to avoid breaking the lobster pieces.
Heat a skillet over medium heat and add butter to melt.
Split the hot dog rolls and place them in the skillet, cut side down.
Toast the rolls until golden brown, about 2-3 minutes.
Remove the rolls from the skillet and place lettuce leaves inside each roll.
Spoon the lobster mixture generously into each roll.
Garnish with extra chives if desired.
Serve immediately with lemon wedges on the side.
Enjoy your delicious homemade lobster rolls!
