Created a montage that contains cheese (4)
I believe the answer is:
edam
'cheese' is the definition.
(Edam is an example)
'created a montage that contains' is the wordplay.
'that contains' indicates the answer is hidden within the clue.
'EDAM' is hidden in the letters of 'created a montage'.
(Other definitions for edam that I've seen before include "Red-coated cheese" , "Dutch food" , "Cheese made in Holland" , "Yellow cheese with a red covering" , "Hard Dutch cheese" .)
