Loathe man cooking pies (7)
I believe the answer is:
despise
'loathe' is the definition.
(I've seen this before)
'man cooking pies' is the wordplay.
'man' becomes 'des'.
'cooking' is an anagram indicator (cook can mean to falsify or distort).
'pies' with letters rearranged gives 'pise'.
'des'+'pise'='DESPISE'
(Other definitions for despise that I've seen before include "Feel contempt for (someone/something)" , "Hate, disdain" , "Hold in contempt" , "Loathe, look down on" , "Abhor" .)
