Blackened Fish Sandwich

Coat fish fillets with melted butter or olive oil. In a small bowl, combine all seasonings and dust the mixture onto the fillets. Heat the remaining oil in a skillet over high heat. Gently lay the fillets onto the very hot skillet, cover, and cook for about 2-5 minutes on each side (depending on thickness) until the fish flakes easily with a fork and the surface is dark brown and crust-like. Spread some yogurt on the SWG buns, and add a slice of tomato and mound of shredded lettuce. Top with the blackened fish and munch away!
