Where to find fruit or vegetables? (8)
I believe the answer is:
orchards
'where to find fruit' is the definition.
'or vegetables?' is the wordplay.
'vegetables?' becomes 'chards' (chard is a kind of vegetable).
'or'+'chards'='ORCHARDS'
(Other definitions for orchards that I've seen before include "Fruits grow in them" , "where fruit is to be found" , "Fruit growing fields" , "Fields of fruits" , "Plantations of fruit trees" .)
