Finely mince the green cabbage and scallion.
In a bowl, mix the ground pork, egg white, cabbage, scallion, coconut aminos, sesame oil, grated ginger, minced garlic, salt, and pepper until well combined.
Place a dumpling wrapper on a clean surface and spoon about 1.5 tablespoons of the pork mixture into the center.
Wet the edges of the wrapper with water, fold in half, and pinch the edges to create a tight seal.
Heat avocado oil in a large non-stick skillet over medium heat.
Arrange dumplings in the pan and cook for 3 minutes until the bottoms are browned and crispy.
Add 3 tablespoons of water to the pan and immediately cover with a tight-fitting lid to steam for 5 minutes.
Remove the lid and continue cooking for 1-2 minutes until the moisture evaporates and the bottoms crisp up again.
Serve the dumplings hot with the chili garlic sauce on the side.
