Instructions:
Heat canola oil in a large nonstick skillet over medium-high. Add bok choy, and cook, stirring often, until wilted and mostly dry, 6 to 8 minutes. Add ginger and garlic; cook, stirring constantly, 1 minute. Transfer bok choy mixture to a plate to cool 5 minutes. Pat the mixture dry with a paper towel.
- Stir together ground pork, bok choy mixture, and crushed red pepper in a medium bowl.
- Place a dumpling wrapper on work surface, and spoon about 1 tablespoon filling in center of wrapper. Using a pastry brush or your fingers, lightly moisten the edges of the wrapper with water. Fold the wrapper over to make a half-moon shape, pressing edges to seal. Repeat process with remaining wrappers and filling.
- Lightly coat air fryer basket with cooking spray. Place 6 dumplings in basket, leaving room between each; lightly spray the dumplings with cooking spray. Cook at 375°F until lightly browned, 12 minutes, turning dumplings over halfway through cooking. Repeat with remaining dumplings, keeping cooked dumplings warm.
- Meanwhile, stir together rice vinegar, soy sauce, sesame oil, brown sugar, and scallions in a small bowl until sugar is dissolved. To serve, place 3 dumplings on each plate with 2 teaspoons sauce
