Fruit and veg given to companion (5)
I believe the answer is:
peach
'fruit' is the definition.
(type of fruit)
'veg given to companion' is the wordplay.
'veg' becomes 'pea' (pea is a type of vegetable).
'given to' means one lot of letters go next to another.
'companion' becomes 'ch' (Companion of Honour).
'pea'+'ch'='PEACH'
'and' acts as a link.
(Other definitions for peach that I've seen before include "Popular stone-fruit" , "Inform on" , "TREE" , "Furry fruit" , "Fruit with downy skin" .)
