Person in country, not in city, starts outdoor meal (6)
I believe the answer is:
picnic
'outdoor meal' is the definition.
(a picnic is a meal outdoors)
'person in country not in city starts' is the wordplay.
'starts' says to take the initial letters.
The first letters of 'person in country not in city' is 'PICNIC'.
(Other definitions for picnic that I've seen before include "Do without" , "Alfresco meal" , "Meal outdoors" , "Outdoor meal (that's easy?)" , "Outdoor snack" .)
