Cabbage wraps last of mince and large sausage (7)
I believe the answer is:
saveloy
'sausage' is the definition.
(I know that Saveloy is a type of sausage)
'cabbage wraps last of mince and large' is the wordplay.
'cabbage' becomes 'savoy' (savoy cabbage is a kind of cabbage).
'wraps' means one lot of letters goes inside another (inserted letters get wrapped up).
'last of' says to take the final letters.
'and' says to put letters next to each other.
'large' becomes 'L' (eg in clothes sizes).
The last letter of 'mince' is 'e'.
'e'+'l'='el'
'savoy' placed around 'el' is 'SAVELOY'.
(Other definitions for saveloy that I've seen before include "One using brains originally" , "Big sausage" , "Highly seasoned pork sausage - love, say (anag)" , "Type of sausage" , "Spicy sausage" .)
