1. Prepare the Wonton Filling

1. Combine Ingredients: In a mixing bowl, combine the ground pork, chopped green onions, soy sauce, sesame oil, grated ginger, minced garlic, salt, and white pepper. Mix well until the filling is evenly seasoned.

2. Assemble the Wontons

1. Lay Out the Wrappers: Place a wonton wrapper on a clean surface. Keep the other wrappers covered with a damp cloth to prevent them from drying out.
2. Add the Filling: Place about 1 teaspoon of the filling in the center of the wrapper.
3. Fold the Wonton: Lightly brush the edges of the wrapper with egg white. Fold the wrapper in half diagonally to form a triangle, pressing out any air around the filling and sealing the edges. Bring the two outer corners of the triangle together and overlap them, sealing with a dab of egg white to form the classic wonton shape.
4. Repeat: Continue with the remaining wrappers and filling, placing completed wontons on a tray lined with parchment paper.

3. Make the Broth

1. Sauté the Aromatics: In a large pot, heat the sesame oil over medium heat. Add the grated ginger, minced garlic, and white parts of the green onions. Sauté for 1-2 minutes until fragrant.
2. Simmer the Broth: Add the chicken broth, soy sauce, and sugar (if using). Bring the broth to a gentle simmer. Add mushrooms, spinach, or bok choy if desired.

4. Cook the Wontons

1. Boil Water: In a separate pot, bring water to a boil. Drop the wontons into the boiling water in small batches to avoid overcrowding.
2. Cook Until Done: Boil the wontons for 3-5 minutes, or until they float to the surface and the filling is fully cooked. Remove with a slotted spoon.

5. Assemble the Soup

1. Combine Wontons and Broth: Divide the cooked wontons among serving bowls. Ladle the hot broth over the wontons.
2. Garnish: Top each bowl with sliced green onions, cilantro, and chili oil if desired.
