Nutty fruit (7)
I believe the answer is:
bananas
This clue is a double definition.
'nutty' is the first definition.
(thesaurus)
'fruit' is the second definition.
(I've seen this before)
(Other definitions for bananas that I've seen before include "Mad - curved fruits" , "hands" , "off 27 [TROLLEY]" , "Crazed" , "Fruit - nuts" .)
