Supper's beginning with fruit and broccoli? (6)
I believe the answer is:
spears
'broccoli?' is the definition.
(broccoli spears are an example)
'supper's beginning with fruit' is the wordplay.
'supper's beginning' becomes 's' (I can't justify this - if you can you should give a lot more credence to this answer).
'with' means one lot of letters go next to another.
'fruit' becomes 'pears' (I've seen this before).
's'+'pears'='SPEARS'
'and' acts as a link.
(Other definitions for spears that I've seen before include "Lances" , "Some broccoli" , "stickers" , "Javelins" , "Bits of green veg" .)
