Fruit counter in centre on right (7)
I believe the answer is:
rhubarb
'fruit' is the definition.
(I've seen this before)
'counter in centre on right' is the wordplay.
I cannot quite understand how this works, but
'counter' could be 'bar' (bar is a kind of counter) and 'bar' is found in the answer.
'centre' could be 'hub' (hub is a kind of centre) and 'hub' is present in the answer.
'right' could be 'r' (common abbreviation) and 'r' is found within the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
(Other definitions for rhubarb that I've seen before include "Purgative stalk" , "this stick is to be swallowed" , "Vegetable used as fruit" , "Word repeated by actors to simulate conversation" , "Hand covering" .)
