Chop the shrimp into small pieces and combine them in a mixing bowl with the chopped cabbage, green onions, minced garlic, and grated ginger.
Add soy sauce, sesame oil, salt, and pepper to the shrimp mixture and mix well to ensure even distribution of ingredients.
Take one dumpling wrapper and place about 1 tablespoon of the shrimp filling in the center. Wet the edges of the wrapper with a little water.
Fold the wrapper in half over the filling and pinch the edges to seal tightly. You can add pleats for a decorative touch.
Repeat the process with the remaining wrappers and filling until all dumplings are made.
Prepare your steamer by lining it with parchment paper or spraying it with non-stick spray. Arrange the dumplings in a single layer, ensuring they are not touching.
Fill a pot with water and bring it to a boil. Place the steamer over the pot, cover it, and steam the dumplings for about 12-15 minutes, or until the shrimp are cooked through.
Once done, carefully remove the steamer from the pot and let the dumplings cool slightly before serving.
