All ingredients ready? Let's begin!
First, make the jalapeno spread by combining the mayonnaise, minced jalapeno, lime juice, and honey in a small bowl. Set aside.
Slice the baguettes lengthwise. Spread the unsalted butter on both sides of the bread.
Place the baguettes on a cookie tray, butter-side facing up and broil until the edges turn light brown.
Rinse the scallops and then pat dry with a towel.
Gently toss the scallops with the Old Bay seasoning.
Heat the cooking oil in a non-stick skillet on medium-high heat. Carefully add the scallops.
Let the scallops cook, without touching them, so they develop a sear on one side. Gently turn the scallops and sear the other side until they are cooked through. This will take about five minutes for both sides. Remove the scallops from the heat.
To build the sandwiches, smear a thin amount of the jalapeno spread on the bottom half of the baguettes.
Place a generous handful of shredded lettuce on top of the smear.
Next, shingle the tomato slices on top of the lettuce.
Place the cooked scallops evenly on top of the tomatoes.
Drizzle the jalapeno spread over the scallops and top with the top half of the baguette.
Serve immediately.
