Anecdotally, when I learned in kollel, I had a long commute.
I would often eat dinner more than an hour after finishing kollel.
On multiple occasions when I was feeling very hungry, I’d get a slice of pizza to hold me over until I got home.
I would have done it more frequently but it gets expensive and unhealthy.
I think this is a classic example of a snack.
And asking around, I’ve heard numerous people doing the same thing- getting a slice before a long commute home from work etc.
It doesn’t contradict the fact that sometimes I eat pizza for dinner.
When it’s a snack I make mezonos.
When it’s a meal I make hamotzi.
I don’t think this is crazy at all.
