Spray two baking sheets with nonstick cooking spray.
Beat the egg white until frothy. Beat in the sugar, salt, cinnamon, and nutmeg.
Stir the pecans into the egg white mixture until well coated. Spread the pecans out over the prepared baking sheets in a single layer. Try to leave a little space between the pecans so they won’t form clumps.
Bake for 1 hour.
Cool the pecans and store in tightly covered containers.
