How Many "Last Meals" Do You Get?

Overnight the Supreme Court issued a last-minute stay of execution less than an hour before a Texas inmate was to be executed by lethal injection for the 1993 murder of his live-in girlfriend and her two sons. According to CNN, the condemned man received this news as he was eating his last meal. There are apparently significant issues concerning DNA testing still to be considered. 


More frivolously, however, I wonder whether, if his execution were to be re-set again for a later date, he would be entitled to another "last meal"? Or is there is a strict "one last meal per person" policy?  If he does get another one, does he have to have the same meal he ordered last night?
