Rob has no hesitation eating a fine dish (6)
I believe the answer is:
pilaff
'rob has no hesitation' is the definition.
I can't judge whether this defines the answer.
'eating a fine dish' is the wordplay.
'eating' is an insertion indicator.
'a fine' becomes 'f' (abbreviation e.g. condition of old coins, books).
'dish' becomes 'pilaf' (pilaf is a kind of dish).
'f' going within 'pilaf' is 'PILAFF'.
Can you help me to learn more?
(Other definitions for pilaff that I've seen before include "Rice dish" , "Rice cooked in well-seasoned broth" .)
