Big cheese Father with container served up
I believe the answer is:
top dog
'big cheese' is the definition.
Both the definition and answer are singular nouns.
Perhaps there's a link between them I don't understand?
'father with container served up' is the wordplay.
'father with' becomes 'god' (I can't explain this - if you can you should give a lot more credence to this answer).
'container' becomes 'pot' (pot is a kind of container).
'served up' says the letters should be written in reverse.
'god'+'pot'='godpot'
'godpot' written backwards gives 'TOP DOG'.
Can you help me to learn more?
(Other definitions for top dog that I've seen before include "Master or victor like superior canine" , "one who's most successful" , "Person in charge" , "Sirius" , "Boss" .)
