Preheat oven to 425 degrees. Spray an oven safe wire cooling rack with non-stick cooking spray and set over a rimmed 18 by 13-inch baking sheet.

In a shallow dish toss together panko, parmesan, parsley, garlic powder, salt and pepper. Drizzle in olive oil and toss well to evenly coat mixture.

In a separate shallow dish beat the egg until yolk and white are well blended.

Working with one piece of salmon at a time dredge each side in egg, then transfer to panko mixture and coat and press both sides of salmon in panko mixture.

Transfer to prepared wire rack on baking sheet. Repeat process with remaining 3 portions.

Bake in preheated oven until salmon is barely cooked through, about 10 - 15 minutes.

Serve with lemon slices for spritzing over.
