In a medium bowl, add garlic, salt, pepper, and steaks. Stir to thoroughly combined; set aside. In a small bowl, combine the cumin, coriander, red wine vinegar, beef broth, and soy sauce. Set aside.
To Prepare the bag of French fries:In a large skillet, heat ½ inch of oil until shimmering. Add the french fries and fry over high heat until golden and crisp, about 3 minutes; drain on paper towels.
For the Lomo Saltado:While the French fries are cooking, drizzle some canola oil in a frying pan or wok.*(enough to completely cover the bottom of the frying pan) over high heat. Please wait until it gets hot, then start Browning half the steaks, brown on one side, flip over, and cook for an additional 2 minutes.
Remove the steak and repeat with the second half,*(stir-fry a few slices of steaks at a time, so they do not steam). Stir-fry each batch for 2 minutes on each side or until golden and crisp.
Remove the steaks from the frying pan, add the onions and the aji Amarillo, with additional oil if needed, cook for about 2 to 3 minutes. Stir in the tomato; cook for just a minute. The tomatoes should hold their shape.
Stir in soy sauce mixture and cook for about 1 to 2 minutes. Taste the lomo saltado for seasoning; add more salt or pepper if needed. Turn off the heat, add chopped cilantro, and serve right away with French fries and white rice. Enjoy our Lomo Saltado!
