Cut off ends of zucchini and put them in the food processor. Process until coarsely ground. Set aside.
Put walnuts and almonds in food processor. Process until coarsely ground.
Mix the walnuts, almonds and zucchini together. Add salt and mix thoroughly.
Spread mixture onto Teflon sheets on dehydrator racks. Score the crackers with a knife. I show how to do this with my Spicy Flax Cracker recipe. Dehydrate at 110° for 24-30 hours, or until dried out. Flip the crackers over after 12 hours or so.
