Girl consuming last of sausage meat (4)
I believe the answer is:
veal
'meat' is the definition.
(veal is a kind of meat)
'girl consuming last of sausage' is the wordplay.
'girl' becomes 'val' (short for Valerie).
'consuming' is an insertion indicator.
'last of' suggests the final letters.
The last letter of 'sausage' is 'e'.
'val' enclosing 'e' is 'VEAL'.
(Other definitions for veal that I've seen before include "Calf meat" , "White meat" , "cuisine" , "Calves' flesh as food" , "Type of meat" .)
