Preheat oven to 250F.
Whip egg whites until frothy. Add grated ginger, fine sea salt, and Vietnamese cinnamon. Keep whipping until the mixture is combined well.
Add raw mixed nuts of your choice to the egg white mixture. Stir to coat.
Spray the parchment paper lightly with coconut oil spray. Spread the nuts evenly onto the baking sheet. Bake at 250F for 40 mins until fragrant, rotate the baking sheet pan at half point.
Once the mixed nuts are cooled and hardened, break them into pieces. Store in an airtight container. If the weather is hot, store them in the refrigerator.
