I suppose we're talking about widely varying things. Here in Europe I think they have both pre-packaged bread and sandwich, which I suppose comes on the same truck as the other stuff. And sth like a Deli section with bread and small pizzas and stuff. That probably comes as frozen/refrigerated dough and is baked there. I'm not really sure if they do it like that at Aldi, but they do that in other stores. And I mean Aldi is just one supermarket chain.
