Heat oven to 300°F. Spray 15x10x1-inch pan with cooking spray. In large bowl, beat sugar, salt, cinnamon, ginger, cloves, nutmeg, water and egg white with electric mixer on high speed 1 to 2 minutes or until mixture is frothy. With rubber spatula, fold in nuts until evenly coated. Spread mixture evenly in pan.
Bake 45 to 50 minutes, stirring occasionally, until nuts are fragrant and toasted. Cool completely in pan, about 30 minutes. Stir in chocolate candies. Store in tightly covered container.
