Preheat the oven to 325 degrees.
Line a metal loaf tin with parchment paper. ( My loaf tin was 10 x 5 x 3-Inch)
In a medium bowl, mix the cinnamon, nutmeg, almond flour, coconut flour, baking soda, baking powder, and salt with a fork until everything is well mixed. Set the bowl aside.
In a large bowl, mix the eggs, honey, vanilla, mashed banana, mashed avocado, and melted coconut oil together with a hand-held electric mixer until the mixture thickens and everything is well mixed.
Pour the dry ingredients into the wet ones and mix with a hand-held electric mixer until well mixed.
Fold in the shredded zucchini.
Pour the mixture into the loaf pan, and bake for 60 minutes.
Let the bread cool for a bit, then lift it out of the loaf tin by lifting up the wax paper on either side of the bread. Peel the wax paper off of the bread, and enjoy!
