Healthy food at home for crusader's foe (7)
I believe the answer is:
saladin
'crusader's foe' is the definition.
(I've seen this in another clue)
'healthy food at home' is the wordplay.
'healthy food' becomes 'salad' (I've seen this before).
'at home' becomes 'in' ('I'm in' can mean 'I'm at home').
'salad'+'in'='SALADIN'
'for' is the link.
(Other definitions for saladin that I've seen before include "Crusade foe of Richard I" , "Enemy of Richard I in the Crusades" , "He fought Richard" , "Richard the Lionheart's enemy" , "Crusade warrior" .)
