PREP: Preheat the oven to 250˚F. Spray a cookie sheet with cooking spray and set aside.
MAKE SUGAR MIXTURE: In a small bowl, mix together the sugar, salt, cinnamon, and nutmeg.
COAT THE NUTS: In a medium bowl, whisk the egg white until it is foamy. Add the pecans and toss to coat in the egg mixture. Add the sugar mixture to the nuts and toss again to coat with the sugar.
BAKE: Spread the nuts in an even layer on the baking sheet and bake in the prepared oven for 60 minutes, stirring every 15 minutes. Allow to cool for 10 minutes before serving or transferring to a container to store.
