Where to find fruit – or vegetable (7)
I believe the answer is:
orchard
'where to find fruit' is the definition.
'or vegetable' is the wordplay.
'vegetable' becomes 'chard' (chard is a kind of vegetable).
'or'+'chard'='ORCHARD'
(Other definitions for orchard that I've seen before include "It produces fruit" , "land for fruit-growing" , "Small cultivated wood" , "Location of fruit" , "Enclosure containing fruit trees" .)
