Lomo Saltado is basically the Peruvian version of a stir fry made with steak, tomatoes and red onions. It’s cooked in an incredibly simple but amazingly savory sauce made of mostly soy sauce and red wine vinegar. Translated the dish literally means ‘salted beef’ and it’s traditionally served with white rice and french fries because as every Peruvian well knows, two carbs are better than one.
While potatoes are roasting, heat a large pot over high heat. Add remaining 2 tablespoons olive oil and sauté mushrooms, garlic, onion and tomato for 3-4 minutes. Add soy sauce, vinegar, broth and Worcestershire and sauté for 1-2 minutes more. Season to taste with salt and pepper.
