In a spacious bowl, mix together the diced shrimp, shredded chicken, chopped napa cabbage, green onions, minced garlic, and ginger. Pour in the soy sauce and sesame oil, then sprinkle with salt and black pepper. Stir thoroughly to ensure all ingredients are well combined.

Take a dumpling wrapper and spoon approximately 1 tablespoon of the filling into the center.

Wet the edges of the wrapper with your fingertip dipped in water. Fold the wrapper over the filling to form a crescent shape and press the edges firmly to seal. You can crimp the edges for a decorative flair if you like.

Continue this process until all the filling is used and the dumplings are formed.

To cook the dumplings, you can choose to steam or pan-fry them. For steaming, arrange the dumplings in a steamer lined with parchment paper and steam for 10-12 minutes. For pan-frying, heat a tablespoon of oil in a skillet over medium heat, add the dumplings, and cook until the bottoms are crispy and golden. Then pour in 1/4 cup of water, cover, and let them steam for an additional 5-7 minutes until fully cooked.

Serve the dumplings warm alongside soy sauce or your preferred dipping sauce for an extra burst of flavor.
