Wasabi Mashed Idaho® Potatoes

  2. Place the wasabi mashed potato in a small pastry bag.
  3. Pipe a small ¼-inch wide line of mashed potato down the middle of the rice, then layer the blanched spinach and grilled asparagus before rolling it up tightly.
  4. Place the tomato filets over the top of the roll all the way up the roll.
  5. Slice into 8 round pieces with a sharp knife.
  6. Garnish each slice with a small squeeze of tamarind sauce, a few soy pearls, and cut chives or scallion tops.
