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