Mexican food and the donkey eating it (7)
I believe the answer is:
burrito
'mexican food' is the definition.
(I've seen this before)
'the donkey eating it' is the wordplay.
'the donkey' becomes 'burro' (term for a small donkey).
'eating' indicates putting letters inside.
'burro' placed around 'it' is 'BURRITO'.
'and' acts as a link.
(Other definitions for burrito that I've seen before include "Tortilla folded around a savoury filling" , "Mexican food" , "Mexican tortilla rolled round a savoury filling" , "that's eaten in Mexico" , "Filled tortilla dish" .)
