Preheat oven to 400 degrees. Line a baking sheet with wax paper. Place oats and walnuts in food processor; pulse until finely chopped. Add salt, black pepper and ginger; pulse two more times to mix well. Remove from food processor; place in pie plate. Place egg whites in another pie plate. Dip turkey in egg, then in oat mixture. Place turkey on baking sheet a few inches apart, rounded side up. Bake for 20 to 25 minutes or until internal temperature reaches 170 degrees. Remove from oven; let cool for 5 to 10 minutes. Slice turkey about ¼ inch thick and serve warm.
