South Africa has boys making healthy dishes (6)
I believe the answer is:
salads
'healthy dishes' is the definition.
(salads are good for you)
'south africa has boys' is the wordplay.
'south africa' becomes 'sa' (abbreviation).
'has' means one lot of letters go next to another.
'boys' becomes 'lads' (lad is a kind of boy).
'sa'+'lads'='SALADS'
'making' acts as a link.
(Other definitions for salads that I've seen before include "Food mixtures of lettuce etc." , "Food mixtures including greens" , "Leafy meals" , "Dishes of letuce etc." , "Healthy meals" .)
