Preheat the oven to 400F. After washing the vegetables, cut them into fry shapes (a mandolin slicer is useful here).
Combine all ingredients and mix well. Lay the fries on a parchment-lined baking sheet in a single layer.
Bake 30-45 minutes or until the fries are crispy, stirring once halfway through. Be careful they don't burn and remove them from the oven at the first sign of browning around the edges. Serve hot.
