Prepare the filling: In a large bowl, combine ground pork, chopped cabbage, green onions, garlic, ginger, soy sauce, and sesame oil. Mix well until fully incorporated.

Fill the dumplings: Place a dumpling wrapper on your palm. Add about 1 teaspoon of filling in the center. Dip your finger in water and moisten the edges of the wrapper.

Fold the dumplings: Fold the wrapper in half and pinch the edges to seal. You can pleat the edges for a traditional look or simply press them together firmly.

Cook the dumplings: Heat vegetable oil in a large non-stick pan over medium heat. Place dumplings in the pan, flat side down, and cook until the bottoms are golden brown (about 2-3 minutes).

Steam the dumplings: Carefully add 1/4 cup water to the pan and immediately cover with a lid. Let the dumplings steam for about 5-6 minutes until the water evaporates and the wrappers are translucent.

Serve: Remove the lid and let the dumplings crisp up for another minute. Transfer to a plate and serve hot with your favorite dipping sauce.
