Preheat oven to 300 degrees F. Spread oats onto a baking sheet and bake for 10-15 minutes, until slightly golden brown. Watch closely to avoid burning.

Spray an 8x8 baking dish with cooking spray and set aside. Increase oven heat to 350 degrees F.

Allow oats to cool for 10 minutes and then mix with chopped apples, almonds, sugar, honey, and salt. Mix well.

In a small bowl, whisk together the egg whites and vanilla. Pour into oat mixture and mix until blended and coated evenly.

Scoop mixture into prepared baking dish and cook for 15 minutes or until golden brown. Cut into 6-8 bars, depending on the desired size.
