Preheat oven to 350. Mix all dry ingredients together in a bowl. In a separate small bowl combine egg white and BBQ sauce. Pour egg mixture over dry ingredients and mix until everything is well coated. Spread granola mixture on a parchment paper lined baking sheet. Bake for 10 minutes, stir, and then bake for 3 more minutes. Remove from oven and let cool to crisp up before serving.
