Cured sliced beef (8)
I believe the answer is:
pastrami
'cured sliced beef' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for pastrami that I've seen before include "Spiced smoked beef" , "Tapered tuck; missile" , "Seasoned smoked beef, served in thin slices" , "Smoked, highly-seasoned cut of beef" , "beef dish" .)
