It's eaten at any time after one (5)
I believe the answer is:
pasta
'it's eaten at any time' is the definition.
I can't judge whether this defines the answer.
'after one' is the wordplay.
'after' becomes 'past' (I've seen this in other clues).
'one' becomes 'a' (a thing is one thing).
'past'+'a'='PASTA'
Can you help me to learn more?
(Other definitions for pasta that I've seen before include "Fusilli, conchiglie and penne" , "Linguine, e.g." , "Course of Italian" , "Rigatoni, tortellini etc" , "Italian foodstuff" .)
