Spiralize the zucchini. I used the KitchenAid Spiralizer Attachment with Peel, Core & Slice to make the spirals. Return the stock to the pot and make it come to a boil again, this time over medium heat.
Add the soup ingredients to the stock and cook for 5 min.
Serve immediately and garnish with chili flakes, toasted sesame and chopped green onions.
