From the Test Kitchen

Flaky tilapia fillets—dusted with a blend of spices like paprika, ground mustard, and cayenne pepper—are sandwiched between crusty, oven-toasted baguettes and creamy rémoulade (a rich combination of mayonnaise, capers, garlic, and more). We’re serving a side of simply roasted sweet potatoes to round out the hearty meal.
