Preheat your oven to 400℉.
Line a 9 or 10 inch metal round pan with parchment paper. If you have corn meal, dust the parchment with it.
Do NOT squeeze out any of the shredded vegetables liquids.
In a bowl, combine the shredded potatoes, carrot, zucchini, flour, grated parmesan, olive oil, onion powder, paprika, garlic powder, salt and pepper to taste and water.
Mix well to make a smooth thick mixture.
Transfer to your prepared pan and flatten out the top evenly.
Sprinkle with a little more grated parmesan and corn meal (if you have it).
Bake for 40-45 minutes or until the top is golden brown.
Once done, allow to set in pan for 10 minutes then transfer to a wire rack to cool 15 minutes.
Slice and enjoy!
