Serve this fish with fresh coleslaw and mashed new potatoes seasoned with butter, whole grain mustard, salt and pepper to make it a meal.
Preheat oven to 400°F.
In a bowl mix together pistachios, bread, mustard, salt and pepper.
In another bowl, separate egg whites from yolks, discard yolks (or reserve for another dish), and whisk whites for 20 seconds.
Pat the codfish very dry with numerous paper towels to remove any water. Season fish with salt and pepper. Dip both sides of the codfish generously in the egg whites. Then coat both sides with pistachio mix, ensuring it is thoroughly coated.
On stovetop, preheat oil in a fry pan over medium heat, adjusting the heat until the oil slightly smokes. Lightly brown the fish on both sides.
Transfer browned fish to a baking sheet and bake on middle rack of the oven approximately 10 to 15 minutes depending on the thickness of the cod (less time for thinner pieces).
