Nah, Australian - you can say 'sandwich' if you like, or sangwidge - I'm very used to 'sanger' and am a bit stumped if it's referred to in any other way. Although of course, I can work it out. I was after all, brought, not dragged, up! Another sanger I like is a tasty cheese, thinly sliced tomatoe with lots of salt and cracked pepper on thickly cut rye bread with thickly spread butter. Very plain, very nice. Yum, yum. A yucky one for me is curried egg sanger. Yuk!
