There is no precise record of who specifically invented Tuna Mornay. However, this dish, which is basically a TUNA CASSEROLE that is very popular in Australia. The difference between the usual fare of Tuna casserole and Tuna Mornay, is that the later uses wheat noodles rather than the egg noodles used in the casserole and may include canned peas and a Morn sauce, which is a Berchamel
sauce with cheese and baked in the oven. Now Mornay sauce is French in origin, but the creative and talented Australians put two and two together and now are renowned for this flavourful and easy to prepare
dish.
