Preheat the oven to 350 degrees. Coat a 9 x 5 loaf pan with avocado oil, or line it with parchment paper.
To a food processor or blender, add the walnuts and blend until the nuts turn into fine flour. Watch that it doesn't blend too much and turns into walnut butter.
In a large bowl add the bananas and mash with a fork until you have fully mashed bananas. Add the eggs, melted coconut oil, and vanilla. Beat with a fork to combine the wet ingredients.
Add the ground walnut flour, coconut flour, cinnamon, baking powder, baking soda, sea salt, and nutmeg. Stir the dry ingredients in until just combined. Stir in the grated zucchini and pour into the prepared loaf pan.
Bake for 50-60 minutes, or until a toothpick comes out clean when inserted into the center. Allow it to cool on a wire rack for 10 minutes before slicing into.
