In a mixing bowl, combine the ground pork, soy sauce, sesame oil, and cornstarch. Mix well until everything is evenly combined.

Take a wonton wrapper and place a teaspoon of the pork mixture in the center.

Wet the edges of the wonton wrapper with a little bit of water, then fold the wrapper in half to create a triangle shape. Press the edges together to seal the wonton.

In a large pot, bring the chicken broth to a boil over medium-high heat.

Once the broth is boiling, add the wontons to the pot and cook for 5-7 minutes, or until the wontons float to the surface and the pork is cooked through.

Divide the wontons and broth among serving bowls, then garnish with sliced green onions.
