Preparation
Combine the walnuts, parsley, orange zest and garlic in a small bowl, mixing well.
Using a Benriner (Japanese mandoline) or other vegetable slicer, thinly shave the sunchokes. Transfer to a bowl and drizzle with the olive oil, tossing well (be sure to coat the sunchokes well, to prevent oxidation). Season with salt and pepper, sprinkle with the gremolata, and serve.
