Leave on empty plate a dried-out vegetable (5,3)
I believe the answer is:
split pea
'dried-out vegetable' is the definition.
'split-pea' can be an answer for 'vegetable' (split-pea is a kind of vegetable). I am unsure of the 'dried-out' bit.
'leave on empty plate a' is the wordplay.
'leave' becomes 'split' (I've seen this before).
'on' says to put letters next to each other (in a down clue, letters appear on others).
'empty' says to hollow out the word (remove centre letters).
'plate' with its centre taken out is 'pe'.
'split'+'pe'+'a'='SPLIT-PEA'
Can you help me to learn more?
(Other definitions for split pea that I've seen before include "What's ready to add to casserole" , "Pulse" , "A stipple (anag.)" , "Dried vegetable" .)
