Sausage and veal cooked in sauce (7)
I believe the answer is:
saveloy
'sausage' is the definition.
(saveloy is a kind of sausage)
'veal cooked in sauce' is the wordplay.
'cooked' indicates an anagram.
'in' means one lot of letters goes inside another.
'sauce' becomes 'soy' (soy sauce).
'veal' anagrammed gives 'avel'.
'avel' inserted within 'soy' is 'SAVELOY'.
'and' is the link.
(Other definitions for saveloy that I've seen before include "Big sausage" , "Highly seasoned pork sausage - love, say (anag)" , "Type of sausage" , "One using brains originally" , "Spicy sausage" .)
