Barbecue bit (3)
I believe the answer is:
rib
'barbecue bit' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for rib that I've seen before include "One of the 12 pairs in the body" , "that was sacrificed for wife originally" , "structural member" , "knitting pattern" , "spare one?" .)
