Old man and woman providing Spanish dish (6)
I believe the answer is:
paella
'spanish dish' is the definition.
(paella is a type of Spanish dish)
'old man and woman' is the wordplay.
'old man' becomes 'pa' (both can mean someone's father).
'and' says to put letters next to each other.
'woman' becomes 'ella' (woman's name).
'pa'+'ella'='PAELLA'
'providing' acts as a link.
(Other definitions for paella that I've seen before include "Spanish dish of rice, chicken, seafood etc cooked in a pan" , "course in Granada?" , "Lap ale with Spanish dish" , "Al, leap into the Spanish dish" , "Saffron-flavoured rice dish" .)
