She provides father with a cooked meal (6)
I believe the answer is:
pamela
'she' is the definition.
'father with a cooked meal' is the wordplay.
'father' becomes 'pa' (pa can mean dad or father).
'with' is an insertion indicator.
'a cooked' indicates an anagram (letters cooked into a new form).
'meal' is an anagram of 'amel'.
'pa' placed around 'amel' is 'PAMELA'.
'provides' acts as a link.
(Other definitions for pamela that I've seen before include "Richardson novel; girl's name" , "Woman" , "Pale MA for the girl" , "Lady" , "Eponymous heroine in Richardson novel" .)
