Prepare the filling – Heat a small amount of oil in a pan. Cook the garlic and ginger until fragrant. Add ground chicken and stir-fry until no longer pink.
Add the vegetables – Mix in cabbage, carrots, and corn. Stir-fry for 3–4 minutes until just tender.
Season – Stir in soy sauce, oyster sauce, sesame oil, MSG, and black pepper. If the filling looks too dry, stir in a lightly beaten egg and cook until set. Let mixture cool completely.
Assemble rolls – Place a wrapper on a flat surface with one corner pointing toward you. Add 2 tbsp of filling near the bottom corner. Fold the bottom up, fold in the sides, and roll tightly. Seal the edge with the flour paste. Repeat for all wrappers.
Fry – Heat oil to 175 °C (350 °F). Fry spring rolls in batches until golden and crispy, about 3–4 minutes per side. Drain on paper towels.
Serve – Enjoy hot with sweet chili sauce, soy sauce, or your favorite dipping sauce.
