The food of love, say? (7)
I believe the answer is:
saveloy
'the food' is the definition.
(saveloy is a kind of food)
'of love say?' is the wordplay.
'of' indicates anagramming the letters (the answer comes from or 'of' the letters).
'love'+'say'='lovesay'
'lovesay' anagrammed gives 'SAVELOY'.
(Other definitions for saveloy that I've seen before include "Spicy sausage" , "Big sausage" , "Type of sausage" , "Highly seasoned pork sausage - love, say (anag)" , "One using brains originally" .)
