During the noon break, I get something to eat (5)
I believe the answer is:
onion
'something to eat' is the definition.
(onion is a kind of food)
'during the noon break i' is the wordplay.
'during' is an insertion indicator.
'break' indicates anagramming the letters.
'noon' anagrammed gives 'onon'.
'onon' placed around 'i' is 'ONION'.
'get' is the link.
(Other definitions for onion that I've seen before include "one understood by expert" , "Alliaceous plant" , "The tear-inducing vegetable" , "Hot dog topping" , "associated with 26 [TRIPE] ?" .)
