From kitchen, a choice snack (5)
I believe the answer is:
nacho
'snack' is the definition.
(I've seen this before)
'from kitchen a choice' is the wordplay.
'from' says the answer is hidden in the clue.
'NACHO' is hidden in the letters of 'kitchen a choice'.
(Other definitions for nacho that I've seen before include "Hot snack" , "Mexican food item" , "Small piece of tortilla with a topping" , "Mexican bite" , "Mexican tortilla chip" .)
