Fried slices of potato (6)
I believe the answer is:
crisps
'fried slices of potato' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for crisps that I've seen before include "Pub snack" , "Common snacks" , "Thin slice of potato fried in deep fat" , "Potato snacks" , "Thin pieces of fried potato" .)
