Chap into fruit, foodie (8)
I believe the answer is:
gourmand
'foodie' is the definition.
(I've seen this before)
'chap into fruit' is the wordplay.
'chap' becomes 'man' (chap can mean a man).
'into' means one lot of letters goes inside another.
'fruit' becomes 'gourd' (gourd is a kind of fruit).
'man' put into 'gourd' is 'GOURMAND'.
(Other definitions for gourmand that I've seen before include "lover of good food" , "he'll swallow plenty" , "Person devoted to eating and drinking" , "Hearty feeder" , "One keen on eating" .)
