Sorry about a student getting no hot food (5)
I believe the answer is:
salad
'no hot food' is the definition.
'salad' can be an answer for 'food' (salad is a kind of food). I'm not sure about the 'no hot' bit.
'sorry about a student' is the wordplay.
'sorry' becomes 'sad' (similar in meaning).
'about' indicates putting letters inside.
'student' becomes 'l' (as in L-plates for learner drivers).
'a'+'l'='al'
'sad' going around 'al' is 'SALAD'.
'getting' is the link.
Can you help me to learn more?
(Other definitions for salad that I've seen before include "Green, potato, Russian or Waldorf?" , "Raw greens, mainly" , "vegetarian dish" , "Lettuce, cucumber etc" , "rabbit food" .)
