See it as an anagram - most undemanding (7)
I believe the answer is:
easiest
'most undemanding' is the definition.
('easy' can be a synonym of 'undemanding')
'see it as an anagram' is the wordplay.
'an anagram' is an anagram indicator.
'see'+'it'+'as'='seeitas'
'seeitas' anagrammed gives '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" .)
