To make these dumplings, start by preparing the filling. Add the ground chicken, sliced green onions, freshly grated ginger, minced garlic, sesame oil, soy sauce, white pepper, and kosher salt to a large bowl. Mix everything together until it is fully incorporated and set it aside.
Next, prepare the dipping sauce. Add the soy sauce, rice wine vinegar, sesame oil, minced garlic, grated ginger, sriracha, sesame seeds, and sliced green onion to a small bowl and whisk until fully combined. Set the sauce aside.
Now, it's time to cook the dumplings! Lightly spray a non-stick skillet with avocado oil and heat it over medium heat. Once the pan is hot, use a cookie scoop to form round balls of the chicken mixture and drop them directly into the pan. Allow the chicken to cook undisturbed for about 2 minutes, then top each ball with a wonton wrapper, gently pressing and pinching the edges of the wrapper around each ball to help it adhere.
Lightly spray the tops of the wonton wrappers with a little more avocado oil spray, then pour ⅓ cup of water around the edges of the pan and immediately cover with a lid.
Allow the dumplings to steam until the water has fully evaporated. Once the water is gone, lift the lid, add another ⅓ cup of water, and repeat this process until the chicken is fully cooked through.
Once the dumplings are done, remove them from the pan and transfer them to a plate, wonton-side up.
Serve them immediately alongside the dipping sauce, and garnish with furikake seasoning and chili oil if desired. Enjoy!
