A Mixed Grill.
Lamb Chop, Pork Chop, Sausage, Steak, Bacon, Liver ( missing in this example replaced with I think Black Pudding - Yuck ), Fried Eggs, Chips, Grilled Tomato, and Fried Onions.
Used to be a Staple menu item just about everywhere, here in Australia. Not anymore due to "Gentrification" of the population.
We're still a young country, so if you discount Vegemite, Lamingtons, Fairy Bread
, Meat pies, Chico Rolls.....I don't think we have a national dish, a Mixed Grill would probably come close.
