Baked Tilapia Fillets with Mustard-Pecan Crust is a delicious and healthy seafood dish. The tilapia fillets are coated in a flavorful mixture of Dijon mustard, crushed pecans, breadcrumbs, and spices. Baking the fillets in the oven gives them a crispy crust while keeping the fish tender and moist. This dish is easy to prepare and perfect for a quick weeknight dinner. Serve the baked tilapia fillets with a side of roasted vegetables or a fresh salad for a complete and satisfying meal.
