Don't be content with a homely meal! (3,3)
I believe the answer is:
eat out
'don't' is the definition.
Both the definition and answer are verbs in their base form.
Perhaps there's an association between them I don't understand?
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for eat out that I've seen before include "Go to restaurant for meal, don't dine at home" , "Use a restaurant" , "Dine away from home" , "Lunch in pub?" , "Have it in cafe" .)
