Combine stock ingredients in a large pot and bring to boil.
Meanwhile, mix the Stock Sauce ingredients together in a small bowl and cut all the vegetables into bite size pieces.
Add the Stock Sauce and mix well to dissolve into the soup. Adjust seasoning as required.
When the stock comes to a boil, place rice stick noodles in the stock, then 1 minute later add the carrots and broccoli, then 1 minute later remove from heat and add the bok choy stems.
Divide the noodles and vegetables between bowls, top with the bok choy leaves and bean sprouts.
Ladle soup into bowls over the vegetables and noodles, and garnish with spring onions.
Optional: finish with chilli oil and more chilli paste - if you can handle the heat!
