Revolving tray (4,5)
I believe the answer is:

'revolving tray' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for lazy susan that I've seen before include "that takes a turn at the tables" , "Revolving table stand" , "Revolving tray on which are condiments etc" , "Eaters help themselves here" , "here pepper-and-salt might put in an appearance" .)
