Lomo saltado:
While frying the potatoes, in a large pan or wok (it's better if you use a wok), heat a tablespoon of oil over high heat. Add the cut of beef and garlic and cook until the meat is browned on all sides. Add the vinegar and cook until half of the liquid has evaporated.
Add soy sauce and broth to the pan and cook for 3 minutes. Next, add the onion, tomato, salt, pepper, and cumin. Cook for another 3 minutes, and finally, add the aji amarillo and cook for one more minute.

On each plate, place some rice, french fries, and lomo saltado. Sprinkle with cilantro leaves, and enjoy your classic Peruvian lomo saltado!
