Preheat the oven to 325 degrees F. Coat a baking sheet with cooking spray.
Whisk 1 egg white in a large bowl until frothy. Add the nuts and stir until evenly coated. Add the spice mix and toss to coat. Spread the nuts in a single layer on the prepared
baking sheet. Bake, stirring occasionally, until toasted and just dry, about 25 minutes.
Let the nuts cool completely on the baking sheet (they will crisp as they cool). Break up any clusters.
