Meal that’s bad to eat unfortunately (4,3)
I believe the answer is:
high tea
'meal' is the definition.
(I know that high tea is a type of dinner time)
'bad to eat unfortunately' is the wordplay.
'bad' becomes 'high' (both can describe rotten or decayed food).
'unfortunately' is an anagram indicator (a bad or unfortunate spelling).
'eat' is an anagram of 'tea'.
'high'+'tea'='HIGH TEA'
'that's' is the link.
(Other definitions for high tea that I've seen before include "A lofty kind of evening meal" , "Early-evening meal" , "Early evening meal" , "Late afternoon meal which includes a cooked dish" , "Late-afternoon meal" .)
