sando noun [C]
UK /ˈsæn.dəʊ/ US /ˈsæn.doʊ/
a type of sandwich made with soft white bread, originating in Japan

“You have to use very fresh, soft, white supermarket bread that mimics the enriched white bread used traditionally in Japan. We know white bread isn’t healthy but here it works because something like sourdough has far too much flavour. Sandos are inverted sandwiches, in a way, because the point is to savour the filling and get almost no flavour from the bread.”
