My daughter inspired me to make this classic Peruvian Stir Fry, Lomo Saltado, and we can't get enough of it! It will definitely satisfy any "meat and potato" lover in your house with the pan-seared steak and french fries!
Slice the potatoes into fries, about ½" thick and 3" long. Toss with the olive oil and salt, and bake until tender when pierced with a fork, 25 to 30 minutes. Before taking them out, turn on the broiler for 1 minute to brown them at the end.
For the steak (on the stovetop)
In a large skillet, heat 1 tablespoon of the olive oil over medium-high heat. Add the steak slices, season with salt and pepper, and cook until brown on the outside and pink in the middle, 4 to 5 minutes. Remove from pan and set aside.
Add the remaining olive oil to the pan and add in the sliced onion, pepper, mushroom, tomato, garlic, and hot pepper. Cook until the veggies are soft and the tomato has released its juices, 5 to 6 minutes.
Pour in the soy sauce, water, and vinegar, and bring to a boil. Turn the heat down to a simmer and put the steak back in along with the fresh cilantro, and stir to combine. Spoon over the oven fries and serve.
