Lobster rolls always hit the spot, and this version is especially enjoyable in halved hot dog buns.
Combine lobster, mayonnaise, lemon juice, chives, salt, and Old Bay, and cayenne if desired, in a small bowl.
Heat butter in a 12-inch skillet over medium-high heat. Working in batches, toast buns until golden brown, about 3 minutes per side, transferring to a paper-towel-lined plate as you work. Fill each bun with 1/4 cup lobster salad.
