Italian sauce for some of Europe's tourists (5)
I believe the answer is:
pesto
'italian sauce' is the definition.
(I've seen this before)
'some of europe's tourists' is the wordplay.
'some of' says the answer is hidden in the clue.
'PESTO' can be found hidden inside 'europes tourists'.
'for' acts as a link.
(Other definitions for pesto that I've seen before include "Pasta sauce variety" , "Basic sauce" , "sauce involving Basil" , "Saucy work" , "Ligurian food" .)
