'dish' is the definition.
I know nothing about this answer so I can't tell whether this works.

'fit for a queen?' is the wordplay.
'fit' becomes 'food' (I can't explain this - if you can you should give a lot more credence to this answer).
'for' means one lot of letters go next to another (I've seen this in other clues).
'a queen?' becomes 'cat' (a queen is a female cat).
'food' put after 'cat' is 'CATFOOD'.
