See it as an anagram - most undemanding (7)
I believe the answer is:
easiest
'most undemanding' is the definition.
('easy' is associated in meaning with 'undemanding')
'see it as an anagram' is the wordplay.
'an anagram' indicates an anagram.
'see'+'it'+'as'='seeitas'
'seeitas' is an anagram of 'EASIEST'.
(Other definitions for easiest that I've seen before include "Most comfortable" , "Most convenient" , "Requiring the least amount of effort" , "most like pie" , "Most simple" .)
