New beginning with plenty of food (7)
I believe the answer is:
noodles
'food' is the definition.
(I've seen this before)
'new beginning with plenty' is the wordplay.
'beginning' suggests taking the first letters.
'with' means one lot of letters go next to another.
'plenty' becomes 'oodles' (I've seen this before).
The first letter of 'new' is 'n'.
'n'+'oodles'='NOODLES'
'of' is the link.
(Other definitions for noodles that I've seen before include "Far Eastern food" , "Simpletons (colloq.)" , "Geese" , "On instrument casually plays" , "Thin strips of pasta for old ones" .)
