Cook the noodles according to the packaging's instructions. Set aside.
To make the sauce, combine the soy sauce, sesame oil, garlic, ginger, granulated sugar, mushroom flavoured stir-fry sauce, and chili sauce in a bowl and mix well.
Heat canola oil over medium heat on a frying pan then add the cremini mushrooms and baby bok choys. Pour about 1 tbsp of the sauce mixture and cook until mushrooms and baby bok choys are soft and tender, about 2 minutes.
Add in the noodle into the pan and pour the rest of the sauce mixture. Cook for about 3 more minutes while stirring the noodle around, making sure it is all coated with the sauce. Turn off heat and mix in green onions to serve.
