Caribbean food is fairly extensive (6)

Ross

I believe the answer is:

widish

'fairly extensive' is the definition.
(somewhat wide)

'caribbean food' is the wordplay.
'caribbean' becomes 'WI' (abbreviation for the West Indies).
'food' becomes 'dish' (dish is a kind of food).
'wi'+'dish'='WIDISH'

'is' is the link.

(Another definition for widish that I've seen is " Rather broad".)

I've seen this clue in The Guardian.
