AirAsia is a low-cost airline. Except for the ticket itself, there is a charge for any service, so it does not include plane meals. If you have already bought a plane ticket, you can manage my reservation at AirAsia official website, where there are value-added services and you can add an airplane meal. There are many choices. The most expensive one seems to be 26 yuan RMB, but if you buy it on the plane, it should be more expensive.
