Fry quickly (5)
I believe the answer is:
saute
'fry quickly' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for saute that I've seen before include "Fried food" , "Fry in a small amount of fat" , "Fry quickly in hot fat" , "fried spuds and the like" , "Cook" .)
