Break to include annual meal (6)
I believe the answer is:
repast
'meal' is the definition.
(repast can mean a meal)
'break to include annual' is the wordplay.
'break' becomes 'rest' (a rest is taking a break).
'to include' is an insertion indicator.
'annual' becomes 'pa' (abbreviation for 'per annum').
'rest' going around 'pa' is 'REPAST'.
(Other definitions for repast that I've seen before include "A formal sort of meal" , "Prates about meal" , "Food - tapers (anag)" , "Banquet" , "A meal concerning time gone by" .)
