Roti de veau Orloff

Veal Orloff, or veal Orlov , is a dish created by Urbain Dubois, a 19th-century French chef employed by Prince Orloff, the Russian ambassador to France. The dish consists of thinly sliced braised loin of veal, with duxelles and soubise layered between the slices, topped with Mornay sauce, and browned in the oven. Similar dishes are popular in Russia today, where they usually go by the name French-style meat (Russian: мясо по-французски, romanized: myáso po-frantsúski). Such varieties often replace veal with cheaper meats, such as beef or pork, have sliced potato added to simpler preparations of mushroom and onion, or replace the Mornay sauce with mayonnaise.
