Throw out her pricey dessert (6,3)
I believe the answer is:
cherry pie
'dessert' is the definition.
(I've seen this before)
'throw out her pricey' is the wordplay.
'throw out' indicates an anagram.
'her'+'pricey'='herpricey'
'herpricey' with letters rearranged gives 'CHERRY-PIE'.
(Other definitions for cherry pie that I've seen before include "Sweet" , "A pudding; a heliotrope" , "Dessert" , "fragrant flower" , "Garden plant - fruit dish with 15" .)
