I am a vegetarian. I don't have any complaints about the quality of airline meal. I am satisfied by what is offered and often my meal appears to be even better than what is served in the general economy class.
However, recently I flew back from Honolulu to Minneapolis. The vegetarian food was not only terrible, the quantitity would have been insufficient even for a two year old! It was barely a spoonful, concealed under much of aluminum foil. The irony was that the sticker said, "specially prepared for ..."

Have you ever been served an airline meal that was grossly inadequate in quantity? I am not talking about a short flight but one in which meals are served.
