Finely chop green onions and Napa cabbage. Set aside.

Place ground pork in a medium mixing bowl. Add sesame oil, hoisin sauce, rice vinegar, soy sauce, egg, salt, and pepper. Mix well.

Add chopped green onions and Napa cabbage to the pork mixture. Mix again until combined.

Fill a large pot with water and bring to a boil. Heat chicken broth in a separate pot.

To fold a wonton, place a wonton wrap in your palm. Place approximately 1 tbsp of filling in the center.

Moisten two edges of the wonton wrap with water. Fold the wonton diagonally, pressing the moistened edges together.

Moisten one corner with water and fold on top of the opposite corner.

Place finished wontons into the boiling water for 3-5 minutes. Wontons are done when they look shriveled against the filling.

Place cooked wontons in hot chicken broth and serve. Garnish with extra green onions if desired.
