One of the world's most luscious sandwiches, the lobster roll is an affordable way to stretch and enjoy this premium ingredient. The humble hot dog bun is traditional here, an important component that won't upstage the star. You can make the mayo-based lobster filling up to a day ahead and keep it refrigerated until just before serving.
5 tablespoons canola mayonnaise
1/4 cup finely chopped celery
3 tablespoons minced onion
2 tablespoons whole milk Greek-style yogurt (such as Fage)
Combine first 7 ingredients in a medium bowl, stirring well. Add lobster to mayonnaise mixture; toss. Cover and chill 1 hour.
Brush butter evenly over cut sides of buns. Heat a large skillet over medium-high heat. Place buns, cut sides down, in pan; cook 2 minutes or until toasted. Line each bun with 1 lettuce leaf; top with 1/3 cup lobster mixture.
