Horrible pasta snacks (5)
I believe the answer is:
tapas
'snacks' is the definition.
(type of Spanish snack)
'horrible pasta' is the wordplay.
'horrible' is an anagram indicator.
'pasta' is an anagram of 'TAPAS'.
(Other definitions for tapas that I've seen before include "taste of Spain?" , "Mediterranean appetisers" , "Spanish appetisers" , "Small Spanish dishes" , "Spanish savoury dishes" .)
