Meal unchanged? This is the wrapped meal you'll see (6,5)
I believe the answer is:
packed lunch
'meal' is the definition.
(type of meal)
I don't understand how the remainder of the clue works.
(Other definitions for packed lunch that I've seen before include "Meal to be carried" , "Ready-prepared midday meal in container" , "Food carried on a day trip" , "Cold meal (eg, taken to school)" .)
