Meaty parts for actors! (4)
I believe the answer is:
hams
'for actors' is the definition.
(ham is a kind of actor)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for hams that I've seen before include "Overacts (colloq.)" , "inept performers" , "Sit on such" , "Poor actors" .)
