Preheat oven to 350 F degrees.
Grease a loaf pan and set aside. You can use cooking spray, or some coconut oil.
In a large bowl mix together whole wheat flour, all purpose flour, salt, baking powder, baking soda, cinnamon and pecans. Set aside.
In another large bowl mash the bananas. Add eggs, vanilla extract, brown sugar and applesauce. Whisk everything together well. Add the dry ingredients to the wet ingredients and using a spatula mix everything until well incorporated.
Pour the mixture into the greased loaf pan and if preferred sprinkle with the rolled oats and Turbinado sugar.
Bake for 50 minutes, or until a toothpick is inserted and comes out clean.
