In a mixing bowl, combine the ground pork or chicken, soy sauce, sesame oil, chopped green onions, grated ginger, and salt. Mix until well combined.

Take a wonton wrapper and place a teaspoon of the meat filling in the center. Moisten edges with water, fold to create a triangle shape, and seal tightly.

In a large pot, bring the broth to a rolling boil. Reduce heat to a gentle simmer.

Drop the wontons into the simmering broth one by one and cook for about 5-6 minutes until they float to the surface.

Add the fresh egg noodles to the pot and cook according to package instructions, usually around 3-4 minutes.

Stir in the bok choy or spinach just before serving and let wilt for 1-2 minutes.

Taste the broth and adjust seasoning with additional soy sauce if necessary.

Ladle the soup into bowls and garnish with chopped green onions and chili oil if desired.
