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' indicates taking the first letters.
'with' says to put letters next to each other.
'plenty' becomes 'oodles' (I've seen this before).
The initial 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" .)
