babybird mentioned chocolate spread on tiger toast, and I thought "Where have I heard that before?"
Answer:

I remember it because chocolate spread on toast, tiger or otherwise, sounds good.
Answer 1 - Possibly a different babybird post.
Answer 2 - A James May video where he makes a sandwich. That's how I landed on this video.
(It could also have been a Lucy Brown video, although it has been a while since she published one of her own.)I tend to think it was a babybird post, because I can imagine me thinking "Mmm. That sounds tasty," but then I remember seeing how tiger toast is made. BUT that really could be a fabricated memory.
But I also recently (three days ago?), saw a post on Discord about how Americans don't know how to make beans on toast. Cooked beans or uncooked (I presume straight out of the can) beans. Which was correct? Well, the two posters posters were from Britain and one did it cooked, the other made it uncooked. So it settled nothing other than demonstrate the words "difference" and "preference" and how both can be true for different people.
Regardless, my mom use to make baked beans on toast when I was a kid. However, I recalled hearing as Pork and Beans, which almost sounds like what James makes here. She also use to make chipped beef on toast. I've had chipped beef on toast since then, and it never tastes the same as it did back then. I think it was my mom's cooking.
