I'm in the UK, never had a pizza roll, still not entirely clear on what one is, but when i was a teenager i did eat a lot of McCain pizza-rollas, which were a sort of soft bread roll filled with pizza topping which you warmed up in the microwave. They were pretty good, probably packed with E-numbers, and a welcome addition at a time before my dad had learned how to cook.
Seen here as part of the broader family of snack-rollas, which had other fillings that weren't as good:
Pizza rolls are like a fried dumpling with pizza filling (meat, sauce, cheese) on the inside. Better if you bake in oven, but almost everyone will microwave. As sad as that turns out, they’re actually very good in a high artificial kind of way. I’m surprised they didn’t make it to the UK; it has UK written all over it.

They stopped making them decades ago.
