Quick and easy. Set the oven to broil. Line a shallow pan with foil. Sprinkle lemon and pepper seasoning on each side of your fillets and place in the pan with a small pat of low sodium butter on top of each. Broil for 3 minutes and then turn over for another 3 minutes (for crappie, longer for thicker fillets like walleye or snapper). Due to Meniere's disease, I've been low sodium for 4 years now.
