Lots going after starter of Neapolitan pasta strips (7)
I believe the answer is:
noodles
'pasta strips' is the definition.
(I've seen this before)
'lots going after starter of neapolitan' is the wordplay.
'lots' becomes 'oodles' (informal term for a large amount).
'going after' is a charade indicator (letters next to each other).
'starter of' indicates taking the first letters.
The initial letter of 'neapolitan' is 'n'.
'oodles' put after 'n' is 'NOODLES'.
(Other definitions for noodles that I've seen before include "Pasta ribbons" , "On instrument casually plays" , "Oriental pasta" , "Geese" , "Simpletons (colloq.)" .)
