Tex-Mex dish (6)
I believe the answer is:
fajita
'tex-mex dish' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for fajita that I've seen before include "Mexican meat strip" , "Wrapped Mexican dish" , "Soft tortilla with filling and grated cheese" , "Cooked meat or vegetables served with a soft tortilla and grated cheese" .)
