Preheat oven to 350 degrees F, line 9 x 5 loaf pan with unbleached parchment paper and spray with cooking spray. Set aside.
In a large mixing bowl, add egg, applesauce, honey, vanilla, cinnamon, baking soda, baking powder and salt; whisk until combined. Add zucchini and stir.
Add flour and mix gently with a spatula just enough to combine.
Pour batter into previously prepared loaf pan and bake for 50-60 minutes or until the toothpick inserted in the middle comes out clean.
Remove from the oven and transfer to a cooling rack to cool off for 10 minutes. Then holding onto the flaps of parchment paper remove bread from a loaf pan and let it cool off for another 30 minutes or completely.
Using sharp serrated knife cut into 12 slices and enjoy!
