A well-known chef is demonstrating his skills in frying something in the staff room while being observed by a Living Skills teacher. Great performance.
potluck - (American English) a meal in which everyone who is invited brings something to eat.[Longman Online Dictionary].
Life is short, so enjoy it while it lasts. Another potluck in the staff room to celebrate the coming school holidays. But this time, we have a "live" cooking session, which adds to the real definition of potluck as well as the excitement of savouring the Westen-themed food. Eat, drink and be merry. Happy holidays to all, put all the schoolwork behind and this applies to the teachers only.
