01 - Heat sesame oil in a large skillet over medium heat. Add minced garlic and grated ginger, sauté 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. Allow filling to cool completely before wrapping.
03 - Place a spring roll wrapper on a clean surface in a diamond orientation. Spoon 2 tablespoons of cooled filling near the bottom corner. Fold the corner over the filling, roll halfway, fold in both sides, and continue rolling tightly. Brush the final edge with cornstarch slurry to seal. Repeat with remaining wrappers and filling.
04 - Preheat air fryer to 390°F.
05 - Lightly spray all sides of the spring rolls with oil. Arrange in a single layer in the air fryer basket, working in batches if necessary to avoid overcrowding.
06 - Air fry for 7–8 minutes, carefully flip the spring rolls, then 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 dipping sauce.
