1 1/2 teaspoons Old Bay Seasoning
1/4 teaspoon cayenne pepper
5 US farm-raised catfish fillets, cut in half

DirectionsIn a large skillet over medium-high heat, heat 3 tablespoons butter and the oil until butter has melted and oil is hot. Saute onions, celery, bell pepper, garlic, salt, and pepper 15 minutes, or until onions begin to caramelize. Remove vegetables to a bowl and cover to keep warm.
In a small bowl, mix Old Bay Seasoning and cayenne pepper. Sprinkle mixture evenly on both sides of fish.

Place 2 fish halves on bottom of each biscuit, top with vegetable mixture, then place top of biscuit over mixture and serve.
