Alfresco meal in breeze (6)
I believe the answer is:
picnic
This clue is a double definition.
'alfresco meal' is the first definition.
(an alfresco meal is eaten outside)
'breeze' is the second definition.
(I know that breeze can be written as picnic)
'in' acts as a link.
(Other definitions for picnic that I've seen before include "food for consumption outside" , "Alfresco repast" , "Informal excursion with meal in open air" , "Do without" , "Take a meal outside" .)
