Like chicken pasty? (5)
I believe the answer is:
ashen
'pasty?' is the definition.
(both can mean pale)
'like chicken' is the wordplay.
'like' becomes 'as'.
'chicken' becomes 'hen' (hen is a kind of chicken).
'as'+'hen'='ASHEN'
(Other definitions for ashen that I've seen before include "Pallid like fire residue" , "Drained of colour" , "Pale (faced)" , "showing signs of anaemia" , "may be pale with shock" .)
