Welcome unwrapped moist cheese (8)
I believe the answer is:
halloumi
'cheese' is the definition.
(I've seen this before)
'welcome unwrapped moist' is the wordplay.
'welcome' becomes 'hallo' (both are greetings).
'unwrapped' means to look at the middle letters (the letters which wrap the word are removed).
'moist' becomes 'humid' (I've seen this in another clue).
The middle of 'humid' is 'umi'.
'hallo'+'umi'='HALLOUMI'
(Other definitions for halloumi that I've seen before include "Cheese from Cyprus" , "Cypriot goat's or sheep's milk cheese" , "Greek dish of fried goat's cheese" , "Traditional Cypriot cheese" .)
