Strips in a diner (5)
I believe the answer is:
bacon
'strips in a diner' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for bacon that I've seen before include "friar" , "Cured pig-meat" , "Meat one can bring home" , "Food - essayist - painter" , "Eg, rashers" .)
