Food some missed, in part (7)
I believe the answer is:
rissole
'food' is the definition.
(rissole is a kind of food)
'missed in part' is the wordplay.
'missed' becomes 'iss' (I can't justify this - if you can you should give a lot more credence to this answer).
'in' is an insertion indicator.
'part' becomes 'role' (eg a theatrical role).
'iss' placed into 'role' is 'RISSOLE'.
'some' is the link.
Can you help me to learn more?
(Other definitions for rissole that I've seen before include "Fried ball of minced food" , "Small pastry" , "Sil rose for the meatball" , "Losers I find in the chopped meat dish" , "Fried small cake of chopped meat" .)
