01 - Heat sesame oil in a large skillet over medium heat. Add minced garlic and grated ginger, sautéing for 1 minute until fragrant.
02 - Add shredded cabbage, julienned carrot, and sliced green onions to the skillet. 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.
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 necessary to avoid overcrowding.
06 - Air fry for 7–8 minutes, then flip and continue air frying for another 5–7 minutes until golden brown and crispy.
07 - Whisk together soy sauce, rice vinegar, sugar, and chili flakes in a small bowl until sugar dissolves.
08 - Serve spring rolls hot while crispy, accompanied by the prepared dipping sauce.
