How to Make It
Preheat oven to 375 ° F.
Place flour on a paper plate. Empty package of potato flakes in another paper plate. Combine eggs and mustard in a shallow bowl. Line a shallow baking pan with non-stick foil. Heat oil in a large sauté pan or skillet over medium heat. Season fillets with salt and pepper and any other seasoning desired.
Dredge fillets first with flour, dip in egg mixture and then in potato flakes. Add fish to pan and cook about 2 minutes per side (until golden). Transfer fish to baking pan and place into oven for about 4 minutes, or until cooked through.
Serve with sauce of choice.
