Sandwich Ingredients

Method

Preparation Instructions

  1. 1

    Prepare the Remoulade Sauce

    In a bowl, mix together mayonnaise, Dijon mustard, chopped capers, pickle relish, lemon juice, hot sauce, paprika, salt, and black pepper. Adjust seasoning to taste. Set aside.

  2. 2

    Cook the Flounder

    Heat olive oil in a skillet over medium-high heat. Coat the flounder fillets with blackening seasoning on both sides. Place the fillets in the skillet and cook for about 3-4 minutes on each side until cooked through and slightly charred.

  3. 3

    Assemble the Sandwich

    Cut the sandwich rolls in half. Place lettuce leaves on the bottom half, followed by the cooked flounder, tomato slices, and a generous dollop of remoulade sauce. Top with the other half of the roll.
