'a menu chips with cold processed ham' is the definition.
I can't judge whether this defines the answer.

'a menu chips with cold processed' is the wordplay.
'with' means one lot of letters go next to another.
'processed' indicates an anagram.
'a'+'menu'+'chips'+'cold'='amenuchipscold'
'amenuchipscold' with letters rearranged gives 'UNACCOMPLISHED'.
