Searches wet assortment for a snack (6,5)
I believe the answer is:
cheese straw
'for a snack' is the definition.
(I've seen this before)
'searches wet assortment' is the wordplay.
'assortment' is an anagram indicator.
'searches'+'wet'='searcheswet'
'searcheswet' with letters rearranged gives 'CHEESE STRAW'.
(Other definitions for cheese straw that I've seen before include "pastry" , "Party snack" , "savoury snack" .)
