Meal cooked outdoors (8)
I believe the answer is:
barbecue
'meal cooked outdoors' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for barbecue that I've seen before include "Outdoor cookery" , "Outdoor party (full of sizzle?)" , "Outdoor eating occasion" , "A picnic with grilled meats" , "Outdoor meal - grill used to cook it" .)
