Herb and I can order stew (9)
I believe the answer is:
coriander
'herb' is the definition.
(coriander is a kind of herb)
'i can order stew' is the wordplay.
'stew' indicates anagramming the letters.
'i'+'can'+'order'='icanorder'
'icanorder' anagrammed gives 'CORIANDER'.
'and' is the link.
(Other definitions for coriander that I've seen before include "leaves for cooking" , "Aromatic herb" , "Plant with spicy fruit" , "Herb used with carrot for soup" , "Spice" .)
