About to have meat and veg in holiday location? (9)
I believe the answer is:
caribbean
'holiday location?' is the definition.
(the Caribbean is a popular holiday destination)
'about to have meat and veg' is the wordplay.
'about' becomes 'ca' (abbreviation for 'circa').
'to have' is a charade indicator (letters next to each other).
'meat' becomes 'rib' (rib is a cut of meat).
'and' means one lot of letters go next to another.
'veg' becomes 'bean' (bean is a type of vegetable).
'ca'+'rib'+'bean'='CARIBBEAN'
'in' is the link.
(Other definitions for caribbean that I've seen before include "who lives on an island?" , "Sort of islander" , "Sea between North and South America" , "Part of Atlantic off Central America" , "Sea south of the US" .)
