It's nothing for me to allow for food (6)
I believe the answer is:
omelet
'for food' is the definition.
(omelet is a kind of food)
'it's nothing for me to allow' is the wordplay.
'it's nothing' becomes 'O' (O resembles 0).
'for' is a charade indicator (letters next to each other).
'to allow' becomes 'let' (synonyms).
'o'+'me'+'let'='OMELET'
(Other definitions for omelet that I've seen before include "American food" , "Light meal" , "Egg dish" .)
