Combine ground pork, shredded zucchini, ground ginger, black pepper, salt, scallions, and egg in a large bowl.

Mix the ingredients thoroughly.

Bring a large pot of water to a rolling boil.

Place about 1 teaspoon of the meat mixture in the center of a dumpling wrapper.

Moisten the edges of the wrapper with a fingertip dipped in water.

Fold the wrapper over to create a triangle or semicircle, depending on the shape.

Pinch the wrapper together using thumbs and forefingers to seal the edges securely.

Drop the dumplings into the boiling water in batches (about 9 at a time).

Cook the dumplings for approximately 8 minutes.

Remove the cooked dumplings from the water using a slotted spoon.

Drain the dumplings briefly on a paper towel before placing them on a plate.

Serve warm.
