But of course there are dishes which can be considered as typical Australian food. People eat a lot of red meat, especially beef. And no wonder, as the beef in this country is among the best in the world. Lamb is also a favourite food and so is pork. Chicken and fish are very important in Australian diet.
Australians eat a great variety of food, but some of the more traditional meals could include roast meat (e.g. lamb and beef, both of which are very popular) and vegetables. Other favourites are meat pies, sandwiches (including vegemite) and a variety of baked or fried foods.
