Salt the zucchini in another bowl with 1/2 tsp of salt and set aside. Do not drain the water that separates from the pulp.
Combine all the flours, xanthan gum, cinnamon, and baking powder in a bowl and whisk well.
Add the zucchini, eggs, and honey and stir well.
Add the pumpkin seeds, sesame seeds, and walnuts and stir the batter until everything is incorporated.
Bake at in a well-greased loaf pan at 350 for an hour or until a toothpick comes out clean! You can bake them in muffin pans and adjust the time to 20-30 minutes depending on your oven, but also check with the toothpick. Store leftovers in the fridge.
