Totally approved by another native! :D Yup, the one on the last photo looks very close. I'd even risk saying, it looks a bit TOO good :D it looks better/tastier than many I often see/eat in little pass-by snack-shops.
Here's a typical one - I had to look for some photo online - because I don't have any (why would I have a photo of somethig so mundane) - this below comes from https://www.tasteatlas.com/zapiekanka/recipe - and apparently from shutterstock
The thing usually is a bit "flatter" thank yours and definitely doesn't have that much meat - they are just made cheap. On the photo you can even see a typical double-paper-french-fries-tray that you get to hold those. Terrible thing to be honest. Now some snackshops use "modern" paper trays bent in a U- or C- shape instead of those old flat ones. Better, but still hard to not make mess with ketchup/breadcrumbs/oil/etc.
Now I want to eat one, eh! :)
