- 2 fish fillets (such as redfish or catfish) - 1 tablespoon olive oil - 1 tablespoon Cajun seasoning - Salt to taste - Fresh lemon wedges for garnish - 2 tablespoons low-fat Greek yogurt - 1 tablespoon Creole mustard - 1 teaspoon lemon juice - Dash of hot sauce (optional)

Rub the fish fillets with olive oil and season generously with Cajun seasoning and a pinch of salt. Heat a cast iron skillet over high heat until it is smoking hot. Place the fish fillets in the skillet and cook for about 3 minutes on each side, or until the fish is cooked through and has a nice blackened crust. In a small bowl, mix together the Greek yogurt, Creole mustard, lemon juice, and hot sauce to make the sauce. Serve the blackened fish with a dollop of Creole mustard sauce on top and garnish with fresh lemon wedges.
