Munch her pricey dessert (6,3)
I believe the answer is:
cherry pie
'dessert' is the definition.
(I've seen this before)
'munch her pricey' is the wordplay.
'munch' indicates an anagram (I've seen 'munched' mean this (letters munched or crushed into a new order)).
'her'+'pricey'='herpricey'
'herpricey' is an anagram of 'CHERRY-PIE'.
(Other definitions for cherry pie that I've seen before include "fragrant flower" , "garden flower" , "Garden plant - fruit dish with 15" , "Sweet" , "Dessert" .)
