2. Stir in carrots, cabbage, mungbean sprouts, and oyster sauce. Cook for 5 minutes, stirring often. Remove from heat and let it cool.
3. Take a spring roll pastry and then scoop about 2 tablespoons of vegetable filling. Place the filling on the diamond-edged of the pastry. Roll inwards until you reach about ¾ of the pastry. Fold in the flaps from left and right and then dab a small amount of water in the diamond-edge opposite from where you started. Close the top flap like an envelope. Repeat for the remaining spring roll pastry and vegetable filling.
4. Preheat your Air Fryer to 380 F (190 C).
5. Place spring rolls in the Air Fryer cooking basket. Spray lightly with oil. Cook for 10 minutes or until golden brown.
