The small size makes them easier and quicker to cook (less likely to burn the outside and leave a frozen center).

As they're pretty strictly meant to be eaten at home the need for a plate of them isn't a big deal.

They have a big brother called a hot pocket that’s like a nasty meat pie. Both will get nuclear meltdown hot and will burn your mouth.

They're more convenient to share with a group, and eat with one hand.

And easier for little kids to eat.

You’re supposed to gobble down a large bowl of them, like jellybeans.
