Nag mom to make something to eat (6)
I believe the answer is:
gammon
'something to eat' is the definition.
(gammon is a kind of food)
'nag mom to make' is the wordplay.
'to make' indicates an anagram.
'nag'+'mom'='nagmom'
'nagmom' anagrammed gives 'GAMMON'.
(Other definitions for gammon that I've seen before include "humbug!" , "Hoax - hock of hog" , "Hind portion of a side of bacon" , "Cured ham; nonsense" , "Bottom piece of a side of bacon" .)
