Called woman to arrange diets (7)
I believe the answer is:
visited
'called' is the definition.
('visit' can be a synonym of 'call')
'woman to arrange diets' is the wordplay.
'woman' becomes 'vi' (short for Violet).
'to arrange' indicates an anagram.
'diets' with letters rearranged gives 'sited'.
'vi'+'sited'='VISITED'
(Other definitions for visited that I've seen before include "Called in (5)" , "came to see" , "Saw" , "Went to see" , "Looked up" .)
