She eats her salad (7)
I believe the answer is:
theresa
'she' is the definition.
(I've seen this before)
'eats her salad' is the wordplay.
'salad' is an anagram indicator (salad can refer to a mixture).
'eats'+'her'='eatsher'
'eatsher' is an anagram of 'THERESA'.
(Other definitions for theresa that I've seen before include "Maria --, Austrian ruler" , "May's one" , "Girl" , "Lisieux saint" , "Maria -, Habsburg empress" .)
