01 - Heat sesame oil in a large skillet over medium heat. Add garlic and ginger, sauté for 1 minute until fragrant.
02 - Add cabbage, carrot, and green onions. Cook for 3–4 minutes until softened. Stir in bean sprouts, soy sauce, and black pepper. Sauté for another 2 minutes, then remove from heat and let filling cool completely.
03 - Place a spring roll wrapper on a clean surface in a diamond shape. Spoon 2 tablespoons of filling near the bottom corner. Fold the corner over the filling, roll halfway, fold in the sides, and continue rolling tightly. Brush the final edge with cornstarch slurry to seal. Repeat with remaining wrappers and filling.
04 - Preheat the air fryer to 390°F (200°C).
05 - Lightly spray all sides of the spring rolls with oil and arrange in a single layer in the air fryer basket. Work in batches if needed to avoid overcrowding.
06 - Air fry for 7–8 minutes, flip, then air fry for another 5–7 minutes until golden and crisp.
07 - Whisk soy sauce, rice vinegar, sugar, and chili flakes together in a small bowl until sugar dissolves.
08 - Serve the spring rolls hot with dipping sauce on the side.
