Started with quiche (4)
I believe the answer is:
tart
'quiche' is the definition.
(thesaurus)
'started with' is the wordplay.
'with' indicates a hidden word.
'TART' is hidden in the letters of 'started'.
(Other definitions for tart that I've seen before include "Sharp tasting- like kind of pie?" , "Sour -- acid" , "Open cake with jam etc" , "Sharp or sour in taste" , "Open-topped pie" .)
