Try holding new chic remodelled Italian dish (7)
I believe the answer is:
gnocchi
'italian dish' is the definition.
(I've seen this before)
'try holding new chic remodelled' is the wordplay.
'try' becomes 'go' (both can mean an attempt).
'holding' means one lot of letters goes inside another.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'remodelled' indicates anagramming the letters.
'go' going around 'n' is 'gno'.
'chic' anagrammed gives 'cchi'.
'gno'+'cchi'='GNOCCHI'
(Other definitions for gnocchi that I've seen before include "Little dumplings" , "2 [PASTA]" , "A course in Rome" , "Starchy food" , "Dough" .)
