Gyoza (Japanese Potstickers)

Prepare the potstickers: Combine ground pork, napa cabbage, green onions, egg, ginger, garlic, soy sauce, Sriracha, and sesame oil in a bowl.

Arrange gyoza wrappers on a flat work surface. Place 1 teaspoon of pork mixture in the middle of each wrapper. Wet edges with your finger or a brush. Fold up sides to form a semicircle; pinch edges to seal.

Heat oil in a heavy skillet over medium-high heat. Add 12 to 15 gyoza to the skillet. Cook until golden brown on the bottom, about 2 minutes. Pour in 1/2 cup water; cover and cook until water is absorbed, 5 to 7 minutes. Transfer gyoza to a plate. Repeat with remaining gyoza.
