01 - Heat sesame oil in a large skillet over medium heat. Add minced garlic and grated ginger, sautéing for 1 minute until fragrant and aromatic.
02 - Add shredded cabbage, julienned carrot, and sliced green onions to the skillet. Cook for 3–4 minutes until vegetables begin to soften. Stir in bean sprouts, soy sauce, and black pepper. Continue sautéing for another 2 minutes, then remove from heat and let the filling cool completely before wrapping.
03 - Position a spring roll wrapper on a clean surface in a diamond orientation. Place 2 tablespoons of cooled filling near the bottom corner. Fold the corner over the filling, roll halfway, fold in both sides, then continue rolling tightly toward the opposite corner. Brush the final edge with cornstarch slurry to seal securely. Repeat with remaining wrappers and filling.
04 - Preheat air fryer to 390°F for optimal crisping.
05 - Lightly coat all sides of the spring rolls with oil spray. Arrange in a single layer in the air fryer basket, cooking in batches if necessary to avoid overcrowding.
06 - Air fry for 7–8 minutes, then carefully flip each spring roll. Continue air frying for another 5–7 minutes until golden brown and crispy throughout.
07 - Whisk together soy sauce, rice vinegar, sugar, and chili flakes in a small bowl until sugar dissolves completely.
08 - Serve spring rolls immediately while hot and crispy, accompanied by the prepared dipping sauce.
