Firm white fish like grouper, tilapia, and mahi mahi are perfect for crusty sandwiches because they won't fall apart after cooking.  “Blackened” shouldn’t be confused with “burnt;” it usually refers to a generous seasoning of hearty spices like paprika and black pepper and a strong sear so that a light crust is formed. It’s ideal in sandwiches with a crusty bread and kicky rémoulade to compete with. Rémoulade is truly the condiment of your dreams—creamy, sweet, and tangy, it’ll be your go-to for dipping chicken tenders or spreading on sandwiches. Grainy mustard will be less pungent than regular Dijon and add great texture from the seeds.

How to Make It

Step 1

Preheat broiler to high with oven rack 8 inches from the heat.

Step 2

Combine paprika, pepper, and salt in a small bowl. Rub spice mixture evenly over fillets.

Step 3

Heat oil in a large nonstick skillet over medium-high. Add fillets to pan; cook 3 to 4 minutes on each side.

Step 4

Combine mayonnaise, relish, mustard, and ketchup in a bowl. Arrange rolls, cut sides up, on a baking sheet; broil 1 minute or until toasted. Spread mayonnaise mixture over cut sides of rolls. Top bottom halves of rolls with lettuce, tomato, fillets, and top halves of rolls.
