Discount permit for some meat (6)
I believe the answer is:
cutlet
'some meat' is the definition.
(cutlet is a kind of meat)
'discount permit' is the wordplay.
'discount' becomes 'cut' (I've seen this before).
'permit' becomes 'let' (synonyms).
'cut'+'let'='CUTLET'
'for' is the link.
(Other definitions for cutlet that I've seen before include "Portion of meat" , "Slice of veal" , "Piece of rib with its meat" , "Lamb or veal chop from behind the neck" , "William -, Piers Plowman author" .)
