Salad we locals prepared (8)
I believe the answer is:
coleslaw
'salad' is the definition.
(coleslaw is a kind of salad)
'we locals prepared' is the wordplay.
'prepared' is an anagram indicator.
'we'+'locals'='welocals'
'welocals' is an anagram of 'COLESLAW'.
(Other definitions for coleslaw that I've seen before include "accompaniment to Salad Days?" , "Salad dish of shredded cabbage, etc" , "Shredded vegetable salad" , "side dish" , "Indeed" .)
