Seasoning in healthy meals (5)
I believe the answer is:
thyme
'seasoning' is the definition.
(thyme is a kind of seasoning)
'in healthy meals' is the wordplay.
'in' indicates a hidden word.
'THYME' is hidden in the letters of 'healthy meals'.
(Other definitions for thyme that I've seen before include "A herb; sounds like prison sentence" , "Seasoning plant" , "Aromatic shrub" , "Plant of the mint family" , "Kind of mint" .)
