It looks like a Cornish pasty and from what I can tell it is the same principle: minced meat with vegetables in a pastry parcel.
Weirdly what I thought was a flour dusting over it is actually icing sugar. Obviously, this gives it a very sweet taste, but it actually works well with the pastry and the reasonably spicy meat, tomato and bean filling.
I then discovered that there are slices of boiled egg in it too which pretty much ruins it for me. It’s a bit like on Masterchef where a contestant just has to learn when to stop adding things until it becomes too much.
It’s an interesting enough snack though!
