In food processor, add 1/2 cup oatmeal and pulse until it is a flour consistency. Add to remaining 1/2 cup of oatmeal and the rest of the dry ingredients. In separate bowl, whisk together egg whites and buttermilk. Add vanilla and applesauce. Fold into dry ingredients, stirring to mix completely. Let batter sit for about 10-15 minutes. On electric griddle coated with cooking spray, pour batter in about 1/3 cup portions. Sprinkle blueberries on top. Cook 1 to 2 minutes, until bubbly. Flip, and continue cooking until lightly browned. Sprinkle on a few more berries and some syrup, if desired and enjoy!
