Staff, embracing new lines, love return of popular pasta dish (10)
I believe the answer is:
cannelloni
'pasta dish' is the definition.
'staff embracing new lines love return of popular' is the wordplay.
I cannot really understand how this works, but
'new' could be 'n' (common abbreviation eg NT for New Testament) and 'n' is present in the answer.
'staff' could be 'cane' (I've seen this before) and 'cane' is located in the leftover letters.
'lines' could be 'll' (I've seen this in other clues) and 'll' is found in the answer.
'love' could be 'o' (In tennis, 'love' means 'zero') and 'o' is present in the answer.
This explanation may well be incorrect...
(Other definitions for cannelloni that I've seen before include "course" , "Italian food" , "Stuffed pasta rolls" .)
