Pop singer Fitzgerald's dish? (6)
I believe the answer is:
paella
'dish?' is the definition.
(type of meal)
'pop singer fitzgerald's' is the wordplay.
'pop' becomes 'pa' (both can mean father).
'singer fitzgerald' becomes 'ella' (I've seen this in another clue).
'pa'+'ella'='PAELLA'
(Other definitions for paella that I've seen before include "Spanish dish of rice, shellfish and chicken" , "Traditional Spanish dish" , "foreign dish" , "Lap ale with Spanish dish" , "Spanish dish of rice, meat and seafood" .)
