Stunt Vegetables?

Obamafoodorama has a  couple posts on a small tempest--it seems Food Network had some sort of cooking challenge between teams of chefs who supposedly were cooking with vegetables from the White House garden.  Except that the show taped the vegetables being harvested one week and being cooked a week later, so it was revealed the actual vegetables cooked weren't the actual vegetables grown in the actual soil of the White House grounds.  Unless and until someone shows the White House has stretched the truth on the kind and volume of harvests from the garden, this strikes me as a non-issue, but it does yield the nice term "stunt vegetables".
