Except that when my son Z says he's making that for breakfast, well, beans are included, and toast is included, but there the resemblance to the normal concept of the dish ends. I should point out that while the graphic recipe pictured here shows what he made the day before yesterday, it is but is one version and other things will be included as and when available.
The double layer of baked beans is important. I'd initially neglected to represent the lower one, and was told that was very necessary in order to soak nicely into the bread, hence it's shown as more sauce than bean.
The bread is usually a delicious sourdough made locally, but apparently even terrible soft white bread will do.
