Waste fried food (7)
I believe the answer is:
fritter
I believe this is a double definition.
'waste' is the first definition.
(frittering is a kind of wasting)
'fried food' is the second definition.
(Other definitions for fritter that I've seen before include "Something battered and fried" , "Hot food" , "Battered food - waste" , "Item cooked in batter" , "Squander - fried dish" .)
