Combine cornmeal, flour and salt on large plate. Brush catfish fillets with Tabasco sauce. Press fish into cornmeal mixture to coat well on both sides. Heat 1 tablespoon each of olive oil and butter in 12-inch skillet over medium heat. Add fillets and cook 4 minutes. With spatula, carefully turn fish. Add remaining oil and butter. Cook 4 minutes longer or until fish flakes easily when tested with a fork. Garnish with lemon wedges.
