Preheat oven to 350 degrees F and grease one bread pan.
Stir together all dry ingredients and set aside.
Lightly beat the eggs and add in the honey, butter, and applesauce.
Stir the dry ingredients into the wet mixture and add zucchini and any optional ingredients, mixing until well combined.
Bake for 45 minutes, a few minutes past a toothpick coming out clean.
Notes
Sugar variation: instead of honey, use 1/2 cup whole cane sugar or to go completely sugar-free, use a 1/2 cup equivalent amount of stevia baking blend.
