In a medium soup pot, bring all the soup ingredients to a boil. Then simmer for 8 minutes. You can remove the garlic and ginger now if desired, and bring it back to a boil to cook wontons. If using fresh wontons, sear them first on both sides, then add them in the soup and cook for 10 minutes. If using frozen wontons, add in the soup and cook for 3-4 minutes. Serve in bowls and garnish with the green onions.
