Never seen those before, I expected you were going to show the other things on the rollers, toquidos rollers or what not? Not sure

They usually have:

Hot dogs (pork/beef/jalapenos/cheese)

Sausages of some kind

Buffalo chicken rollers or such

Toquidos

Jamaican beef patties

All of which are not very good, unless you are drunk, then you don’t understand why you don’t eat them more.
