Food insurance 

Food insurance is a second meal ordered at the same time as your original meal. It is used as insurance in case you are still hungry. Not to be confused with a side order.

Chris got the Mac and cheese platter as food insurance. He is never sure if the spaghetti pizza will be enough.
