Note a bit of meat, cut, will do for Mexican dish (5)
I believe the answer is:
nacho
'mexican dish' is the definition.
(I've seen this before)
'note a bit of meat cut' is the wordplay.
'a bit' suggests taking the first letters (I've seen 'bit of' mean this).
'of' becomes 'o''.
'meat' becomes 'ach' (I can't justify this - if you can you should give a lot more credence to this answer).
'cut' is an insertion indicator (some letters have cut into others).
The first letter of 'note' is 'n'.
'n'+'o'='no'
'no' going around 'ach' is 'NACHO'.
'will do for' acts as a link.
Can you help me to learn more?
(Other definitions for nacho that I've seen before include "Tortilla crisp" , "Mexican snack item" , "Hot snack" , "chip production line unit" , "Tortilla chip topped with cheese and spices" .)
