Chinese-American dish (4,4)
I believe the answer is:
chow mein
'chinese-american dish' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for chow mein that I've seen before include "Chinese dish of noodles, meat and veg" , "Chinese-style noodle dish" , "Chinese-style dish of shredded meat(s) and fried noodles" , "Chinese-American dish" , "Chinese noodle dish" .)
