Mexican tortilla with savoury filling (7)
I believe the answer is:
burrito
'mexican tortilla with savoury filling' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for burrito that I've seen before include "Mexican food" , "that's eaten in Mexico" , "Tortilla folded around a savoury filling" , "Mexican dish of tortilla folded around a filling" , "Filled tortilla dish" .)
