In a large pot, heat water/veggie broth over medium-high heat. Sauté the bok choy, celery, vegetable broth and water.
Bring to boil, cover and simmer for about 7-8 minutes.
Add the rest of the ingredients and boil until the soba noodles are soft, about 3-4 minutes.
Garnish with extra cilantro and serve. Enjoy!
