Preheat the oven to 350 degrees F. Prepare two loaf pans with cooking spray.
Mash the bananas and grate the zucchini and set aside.
Using a mixer, blend together the eggs, sugars, vanilla and oil.
Add the flours, baking soda, powder and salt and mix well.
Add in the pecans, bananas and zucchini and mix until blended.
Pour the batter evenly into the loaf pans and bake for 45 minutes or until a toothpick inserted in the center comes out clean.
Allow the loaves to cool completely then remove from the pans and slice.
