Food calling for father's thanks (5)
I believe the answer is:
pasta
'food' is the definition.
(I know that pasta is a type of food)
'father's thanks' is the wordplay.
'father's' becomes 'pa's' (pa can mean dad or father).
'thanks' becomes 'ta' (UK informal version of 'thank you').
'pas'+'ta'='PASTA'
'calling for' acts as a link.
(Other definitions for pasta that I've seen before include "Basis for serving" , "Staple food of Italy" , "Eg, spaghetti" , "eg Tortellini" , "Tapas (anag)" .)
