Keep the seasoning and sauce sachets when preparing the noodles. Boil water in a saucepan and cook the noodles as per the package instructions, adding the frozen vegetables in the final 30 seconds. Drain thoroughly.
Put the cooked noodle and vegetable mixture into a large bowl. Stir in the oyster sauce, half of the sliced shallots, and the reserved seasoning and sauce. Then mix in the cooked chicken until everything is evenly combined.
Prepare a baking tray by lining it with baking paper. Fill a big bowl with warm water. Briefly soak a rice paper sheet in the water for about 30 seconds until it becomes soft but still easy to handle. Lay it flat on a board.
Scoop about a quarter cup of the noodle mixture onto the bottom of the softened rice paper. Fold in the sides and roll it up tightly to encase the filling. Place the roll on the baking tray and repeat with the remaining sheets and filling. Lightly spray the rolls with oil and sprinkle with sesame seeds.
Cook the rolls in batches in the air fryer at 200°C for 15 minutes or until they turn golden and crispy.
While the rolls cook, mix the sweet chilli sauce, lime juice, and the remaining shallots in a small bowl to make the dipping sauce.
Serve the crispy rice paper noodle rolls warm with the prepared dipping sauce on the side.
