Afternoon meal (4,3)
I believe the answer is:
high tea
'afternoon meal' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for high tea that I've seen before include "Late afternoon meal which includes a cooked dish" , "Late-afternoon meal" , "Early-evening meal" , "A lofty kind of evening meal" , "Early evening meal" .)
