Sauce recipes, tomato included (5)
I believe the answer is:
pesto
'sauce' is the definition.
(pesto is a type of sauce)
'recipes tomato included' is the wordplay.
'included' indicates a hidden word (I've seen 'includes' mean this).
'PESTO' is hidden within 'recipes tomato'.
(Other definitions for pesto that I've seen before include "Basil-based sauce" , "Green sauce" , "Sauce of basil, pine nuts, etc" , "Italian sauce containing basil" , "Basic sauce" .)
