More than just a snack (4)
I believe the answer is:
meal
'more than just a snack' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for meal that I've seen before include "Ground grain or pulses" , "Meat and two veg plus dessert, perhaps" , "Coarsely ground grain" , "Scoff" , "Food ground up" .)
