In a large mixing bowl, combine the ground pork, finely chopped cabbage, soy sauce, minced garlic, grated ginger, sesame oil, and black pepper. Mix until well incorporated.

Take one dumpling wrapper and place it in your palm. Spoon approximately 1 tablespoon of the pork mixture into the center. Lift the edges and pinch to create a half-moon shape.

Moisten the edges of the wrapper with a little water and firmly press to ensure a good seal. Repeat with remaining wrappers.

Preheat a non-stick skillet over medium heat, add oil, and place dumplings in the skillet, sautéing for 2-3 minutes until golden brown.

Pour in enough water to reach about one-third the height of the dumplings and cover the skillet. Steam for 8-10 minutes.

Remove the lid and let any excess water evaporate. Increase heat to crisp for another 1-2 minutes.

Transfer dumplings to a serving plate and serve with dipping sauces like soy sauce and vinegar.
