Father and girl making Spanish dish (6)
I believe the answer is:
paella
'spanish dish' is the definition.
(I've seen this before)
'father and girl' is the wordplay.
'father' becomes 'pa' (pa can mean dad or father).
'and' means one lot of letters go next to another.
'girl' becomes 'ella' ().
'pa'+'ella'='PAELLA'
'making' acts as a link.
(Other definitions for paella that I've seen before include "Spanish course" , "Spanish dish of rice, chicken, seafood etc cooked in a pan" , "Fare for Spaniard" , "Dish (not English)" , "Meal" .)
