Uneasy feeling that a meal is badly cooked (7)
I believe the answer is:
malaise
'uneasy feeling' is the definition.
(I've seen this before)
'a meal is badly cooked' is the wordplay.
'badly cooked' is an anagram indicator (I've seen this in other clues).
'a'+'meal'+'is'='amealis'
'amealis' is an anagram of 'MALAISE'.
'that' acts as a link.
(Other definitions for malaise that I've seen before include "Feeling of illness or mental uneasiness" , "sickness" , "General feeling of discomfort" , "Unease; lethargy" , "Out-of-sorts feeling" .)
