Food that cooks have made plain (4-3-3,3)
I believe the answer is:
'food' is the definition.
I know nothing about this answer so I can't judge whether this works.
'cooks have made plain' is the wordplay.
'cooks' is an anagram indicator.
'havemadeplain' anagrammed gives 'VEAL-AND-HAM PIE'.
'that' is the link.
Can you help me to learn more?
