Preheat the oven to 200 levels. Line a rimmed baking sheet with parchment paper, and dwelling it on the center rack of the oven. Peel the carrots, parsnips, and potato, and grate them on the big holes of a field grater. Place the grated greens on a tidy kitchen towel, fold it around them, and squeeze tightly to clutch all extra moisture. Switch the grated greens to a huge mixing bowl. Add the sliced scallions, flour, and salt and pepper, and toss to mix effectively. Add the evenly crushed eggs, and blend effectively.
