Sliced pie to me is best example (7)
I believe the answer is:
epitome
'best example' is the definition.
(I've seen this in another clue)
'sliced pie to me' is the wordplay.
'sliced' indicates anagramming the letters.
'pie' anagrammed gives 'epi'.
'epi'+'to'+'me'='EPITOME'
'is' acts as a link.
(Other definitions for epitome that I've seen before include "Exemplar - embodiment" , "ie Tempo (anag.)" , "Personification" , "Paradigm" , "classic example" .)
