According to the full documentation, soup is a salad, salad is either quiche or nachos depending on prep style, and nigiri is toast. Notably, salad itself does not fall under the "salad" cube rule.
i would say hot dogs are borderline, with most hot dog buns there is only a very thin bit connecting the two sides, and it's not unusual for that to rip out so you end up with a technically accurate sandwich.
100 years after sliced bread was invented; bread that doesn't stale and doesn't mold for 2 weeks on a counter-top, and still Europe is baffled.
There are reasons to add sugar to bread, quite a lot actually. It causes faster fermentation, increases the Maillard reaction, can make the bread softer, prevents going stale, etc.
I'm not defending subway in particular: they are terrible. But it's not because they add sugar to their bread dough. And Europe pretending this isn't bread is food elitism that ignores that massive differences in production and culture.
that is more sugar than bread
Also very hyperbolic. Subway has 4% sugar, which is high but not cake. Cake recipes are often 25-50% sugar.
To be fair, that 4% is double the max limit to be called bread in Ireland, potentially more if it's 4% of the whole recipe as opposed to 4% of the flour weight.
