Girl taking a friend something to eat (6)
I believe the answer is:
salami
'something to eat' is the definition.
(salami is a kind of food)
'girl taking a friend' is the wordplay.
'girl' becomes 'sal' (feminine given name**).
'taking' means one lot of letters go next to another.
'a friend' becomes 'ami' (I've seen this before).
'sal'+'ami'='SALAMI'
(Other definitions for salami that I've seen before include "Savoury snack" , "Italian sausage (a kind of tactics?)" , "meat product" , "Hooked" , "Highly-spiced sausage" .)
