A high key snack to me would involve 2 separate prep phases.
For instance making crackers involves making the dough then baking which makes it more of a task than cooking a bag of chicken nuggets, which is more of a wait than celery dipped in peanut butter.
I consider these the three teirs of snack making. Anything more and you have entered meal territory.
I wouldn’t have realy thought so, but since you are getting the downvotes, I guess you are right! I’ll upvote you since you’ve apparently found a taboo subject.
