This recipe has a mild level of spice, just enough to be flavorful without overwhelming your tastebuds. If you love extra-spicy foods, pump up the spice by adding sriracha to your finished soup.
Add vegetable broth, 2 TBSP soy sauce, red pepper flakes, and Chinese Five Spice to the saucepan. Bring to a boil and then simmer until ready to serve.
