So hot meal can be really distasteful (9)
I believe the answer is:
loathsome
'really distasteful' is the definition.
'loathsome' can be an answer for 'distasteful' (synonyms). I'm not certain of the 'really' bit.
'so hot meal can be' is the wordplay.
'can be' indicates anagramming the letters.
'so'+'hot'+'meal'='sohotmeal'
'sohotmeal' is an anagram of 'LOATHSOME'.
Can you help me to learn more?
(Other definitions for loathsome that I've seen before include "Hateful" , "15 [ABHORRENT]" , "Repulsive" , "Horrid" , "gross" .)
