  1. Shock the soba noodles in a fresh ice water bath.
  2. Remove, shake off any excess water and place 4 oz into each of the 4 bowls.
  3. Add about 4 ounces of the Soba Sauce onto and around the noodles.
  4. Divide the vegetables onto four plates that are lined with tempura paper (you can use cocktail napkins or large palatable leaves in lieu of the tempura paper) and garnish with a small pile of shichimi togarashi (Japanese chili pepper spice, this can be added to the soba sauce or to the tempura).
  5. Place a small dollop of wasabi paste on the side of the bowl (this will be mixed into the soba sauce).
  6. Garnish the top of the soba noodles with finely sliced green onion and kizami nori (fine julienne of toasted nori).
  7. Eat immediately. You can dip your tempura vegetables into your soba sauce. Enjoy!
