Ingredients
  

The Stir-Fry
  • 1 lb 450g sirloin or tenderloin steak, cut into strips
  • Salt and freshly ground black pepper to taste
  • 3 tbsp vegetable oil divided
  • 1 large red onion sliced into thick wedges
  • 2 plum tomatoes sliced into thick wedges
  • 1 aji amarillo pepper seeded and sliced into strips (or substitute with yellow bell pepper + pinch of cayenne)
  • 2 cloves garlic minced
  • 1 tbsp ginger minced (optional)
The Sauce
  • 3 tbsp soy sauce
  • 1.5 tbsp apple cider vinegar or red wine vinegar
  • 1 tbsp oyster sauce optional for extra umami
  • 1/2 cup beef broth
To Serve
  • 1/2 cup fresh cilantro chopped
  • 1 lb French fries prepared
  • Steamed white rice

Method
 

Preparation
  1. Slice the beef against the grain into 1/2-inch thick strips. Season generously with salt and pepper.
  2. Prepare all vegetables: slice onions and tomatoes into thick wedges so they hold their shape. Mince garlic and ginger. Slice the aji amarillo.
  3. Whisk together the soy sauce, vinegar, oyster sauce, and beef broth in a small bowl.
Stir-Frying
  1. Heat a wok or large heavy skillet over very high heat. Add 1 tbsp oil and wait until it smokes.
  2. Add half the beef in a single layer. Sear without moving for 1 minute to get a nice crust. Flip and cook for another minute until browned but not fully cooked through. Remove and set aside. Repeat with remaining beef.
  3. In the same wok, add another tbsp of oil. Add the red onions and stir-fry for 1-2 minutes until they get some char but are still crunchy. Remove and set aside.
  4. Add the remaining oil. Add the tomatoes and aji amarillo. Stir-fry for 1 minute—do not overcook the tomatoes. Add the garlic and ginger, stir for 30 seconds until fragrant.
Combining
  1. Add the beef and onions back into the wok. Pour in the sauce mixture.
  2. Toss everything together for 1-2 minutes until the sauce slightly thickens and coats everything.
  3. Turn off the heat and toss in the chopped cilantro and the prepared French fries (traditional) or serve the fries on the side.
Serving
  1. Serve immediately with a side of steamed white rice. The combination of the juice soaking into the rice and fries is what makes this dish legendary.
