Place cauliflower “popcorn” pieces into a large ziplock bag and coat with melted butter. In a food processor add nuts (or seeds), Parmesan (or nutritional yeast) and sea salt, process until finely ground. Pour over florets and close top. Shake bag until cauliflower is coated. Place in a dehydrator. Dehydrate at 110 degrees for 6 hours, or until slightly crunchy. If you want it really crunchy, dehydrate for 10 hours. If you fully dehydrate the cauliflower, it will have a week shelf life! What a great camping trip food!
