In a bowl, whisk together the egg white, water and vanilla until frothy. Add the nuts and toss in the mixture. Over the nuts, pour the sugar, salt, cinnamon and nutmeg and toss until coated. Bake at 325 for 45 minutes, or until the nuts are crunchy and the coating is firm on the nuts. At the 20 minute mark, remove the pan from the oven and stir. Continue to cook until all of the nuts are dry and cooked. Remove from the oven and let cool. Once cool they can sit on your counter for about a week, in your fridge for a month or in your freezer for 6-12 months. Serve as a snack or on your favorite salads or desserts.
