Plane carrying meals not able to provide sandwiches (5,3)
I believe the answer is:
table top
'plane' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'meals not able to provide sandwiches' is the wordplay.
'sandwiches' indicates the answer is hidden within the clue (the answer is sandwiched in by the clue).
'TABLE-TOP' is hidden within 'meals not able to provide'.
'carrying' acts as a link.
(Other definitions for table top that I've seen before include "Work surface" , "Head of board" .)
