Group of people eating last of super meal (6)
I believe the answer is:
brunch
'meal' is the definition.
(brunch is a kind of meal)
'group of people eating last of super' is the wordplay.
'group of people' becomes 'bunch' (I've seen this before).
'eating' indicates putting letters inside.
'last of' says to take the final letters.
The last letter of 'super' is 'r'.
'bunch' placed around 'r' is 'BRUNCH'.
(Other definitions for brunch that I've seen before include "Late morning repast" , "Combination breakfast and lunch" , "Late-morning meal" , "11am meal?" , "combined meal" .)
