Puree veggies in food processor. Add in flax seed and seasonings (if desired) and pulse to mix. Drizzle in enough water to make a spreadable batter – like the consistency of mashed bananas. Spread out onto paraflex lined dehydrator sheet(s) and dry at 110-115 for 6-8 hours.
After about 4-5 hours of dry time, flip them over onto the dehydrator tray (with no sheet on it). Continue to dry until not gooey but still flexible.
