Step 1

Thaw langostino tails in the refrigerator overnight, or thaw under cold, running water. Then drain well and pat dry.

Add langostinos and cook until warmed through. Toss to combine and coat the langostinos in butter.

Step 7

Melt remaining 2 tbsp. butter for 15 - 20 seconds in the microwave. Set aside.

Step 8

Spoon langostino mixture evenly into rolls and drizzle with remaining melted butter.
