Father meets a girl - a Spanish dish (6)
I believe the answer is:
paella
'a spanish dish' is the definition.
(paella is a type of Spanish dish)
'father meets a girl' is the wordplay.
'father' becomes 'pa' (pa can mean dad or father).
'meets' says to put letters next to each other.
'a girl' becomes 'ella' (girl's name).
'pa'+'ella'='PAELLA'
(Other definitions for paella that I've seen before include "Dish made of rice, shellfish and chicken" , "Fare for Spaniard" , "course in Granada?" , "Traditional Spanish dish" , "foreign dish" .)
