Cornmeal-Crusted Catfish Sandwiches

For the catfish:
Heat oven to 425ºF. Line a baking sheet with foil and spray with cooking spray.

Whisk cornmeal, Old Bay seasoning, cumin, salt, pepper and cayenne pepper in a shallow bowl. Pour milk into a separate shallow bowl. Dip catfish fillets, one at a time, into milk and then into cornmeal mixture, turning to coat. Transfer to prepared baking sheet. Spray tops lightly with cooking spray.

Bake catfish, flipping halfway through, until golden brown on the outside and flaky on the inside, about 15 to 20 minutes. Let sit at room temperature for 2 minutes before assembling sandwiches.

For the sauce:
Combine all ingredients for the lemon-caper dill sauce in a small bowl.

To assemble the sandwiches:
Spread on half of the sauce on each sandwich bun. Top with a catfish fillet, lettuce and tomato. Serve with lemon wedges, if desired.
