Instructions

Step 1: Preheat grill or grill pan to medium-high heat. Brush 2 whitefish fillets with 2 tbsp olive oil and season with salt and black pepper. Grill for 4-5 minutes per side until fish flakes easily.
Step 2: In a small bowl, mix 1/4 cup mayonnaise, 2 tbsp freshly squeezed lemon juice, 1 minced garlic clove, 1 tsp Dijon mustard, and 1 tbsp olive oil. Season with salt and pepper to taste to make lemon aioli.
Step 3: Warm 2 ciabatta rolls on the grill for 1-2 minutes until slightly toasted.
Step 4: Lightly toss 8 oz crab meat with a drizzle of olive oil and a pinch of salt.
Step 5: To assemble each sandwich, spread lemon aioli on both halves of the rolls, layer 2 leaves butter lettuce, 2 slices tomato, half the grilled whitefish fillet (flaked), and half the crab meat.
Step 6: Close sandwiches and serve immediately with your favorite side.
