Under Irish law (VAT), bread can have up to 2 percent of flour weight in sugar, Subway breads are 10 percent sugar, so according to a court, they aren't bread and have to be taxed under Irish law.
I find Subway bread squshy and not particularly satisfying. However, when we are traveling (back when we could!), Subway is our fast food choice when we do not have our own with us. Although we both get the whole grain, I'm somewhat dubious about the whole grain content.
