Munch, eating for example, nut (6)
I believe the answer is:
cashew
'nut' is the definition.
(cashew is a kind of nut)
'munch eating for example' is the wordplay.
'munch' becomes 'chew' (I've seen this before).
'eating' is an insertion indicator.
'for example' becomes 'as' (I've seen this in other clues).
'chew' going around 'as' is 'CASHEW'.
(Other definitions for cashew that I've seen before include "Common type of nut" , "snack perhaps" , "Edible nut" , "Chew as you would this nut" , "nut-tree" .)
