Appetising, being of Rita's type (5)
I believe the answer is:
tasty
'appetising' is the definition.
(I've seen this before)
'of rita's type' is the wordplay.
'of' indicates a hidden word.
'TASTY' is hidden within 'ritas type'.
'being' acts as a link.
(Other definitions for tasty that I've seen before include "Like nice grub" , "Appetizing" , "With a nice flavour" , "Scrumptious" , "Having good flavour" .)
