Ingredients

Instructions

  1. Step 1: In a medium bowl, toss 1 lb peeled and deveined large shrimp with 2 tbsp Cajun seasoning and 2 tbsp olive oil until shrimp are evenly coated. Let marinate for 10 minutes at room temperature.
  2. Step 2: While shrimp marinate, prepare the remoulade by whisking together 1/2 cup mayonnaise, 1 tbsp Dijon mustard, 1 tbsp lemon juice, 1 tsp Worcestershire sauce, 1 tsp hot sauce, 1/2 tsp garlic powder, and 1/2 tsp paprika in a small bowl until smooth and creamy.
  3. Step 3: Preheat a grill or grill pan over medium-high heat. Grill the shrimp for 2-3 minutes per side until opaque and slightly charred.
  4. Step 4: Slice 4 French rolls lengthwise without cutting all the way through. Spread about 2 tbsp remoulade inside each roll, layer with 1 cup shredded romaine lettuce, 2-3 grilled shrimp, and 1-2 slices of tomato. Serve immediately for a flavorful and satisfying sandwich.
