Outdoor cooking (8)
I believe the answer is:
barbecue
'outdoor cooking' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for barbecue that I've seen before include "Portable grill for cooking outdoors" , "Meal cooked outside" , "garden party" , "Meal outdoors cooked on a grill" , "Alfresco meal" .)
