Sad about a chap not getting a hot meal (5)
I believe the answer is:
salad
'meal' is the definition.
(I have seen 'Cold meal ' mean 'salad' so perhaps 'meal' could also mean 'salad')
'sad about a chap' is the wordplay.
'about' is an insertion indicator.
'a chap' becomes 'al' ().
'sad' placed around 'al' is 'SALAD'.
'not getting a hot' is the link.
This may not be right. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for salad that I've seen before include "Cold vegetable dish" , "Cold dish of vegetables or fruits" , "See 22" , "- Days (musical)" , "Healthy dish" .)
