If you go to Mexico to eat, as I used to when I lived at the border in Lukeville, Arizona (I worked at Organ Pipe Cactus National Monument--right next to the Mexican town of Sonoyta, Sonora), you ate "Milanesa." A friend of mine who spent a lot of time in Eurpoe pointed out that this was what they called the dish when she ate it in Italy, meaning it was beef cooked "Milan Style." So the Mexican menus still credit it to its origins, but here it's just named by how it's cooked.
