Ah, Daniel Craig's heading off for meal in Leon (9)
I believe the answer is:
enchilada
'meal in leon' is the definition.
The definition and answer can be both things that one consumes for nourishment as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'ah daniel craig's heading off' is the wordplay.
'heading' says to take the initial letters (head could mean the top letter).
'off' indicates an anagram.
The initial letter of 'craig' is 'c'.
'ah'+'daniel'+'c'='ahdanielc'
'ahdanielc' anagrammed gives 'ENCHILADA'.
'for' is the link.
Can you help me to learn more?
(Other definitions for enchilada that I've seen before include "Mexican dish" , "spicy dish" , "hot dish" , "wrap" , "Hot food" .)
