Instructions
Prepare the aji sauce. Combine romaine, olive oil, cilantro, green onions, jalapeno, garlic, salt, and pepper in a blender. Puree until smooth and set aside.
Marinate the beef. Combine olive oil, soy sauce, vinegar, cumin, salt, and pepper. Pour mixture over beef, turning to coat. Let sit for 10 minutes.
Preheat frying oil to 350 degrees. Fry french fries until golden and crispy. Drain on paper towels and set aside. Alternatively, cook fries in an air fryer according to the directions on the package.
Heat oil in a large saute pan over medium-high heat. Add beef and saute until browned on both sides. Remove from heat and set aside.
Add the onions in the same pan and saute until softened, about 2-3 minutes. Add the tomatoes, garlic, and aji amarillo paste. Cook until softened, about 2-3 minutes. Add soy sauce and red wine vinegar and simmer for 1 minute.
Return the beef to the pan along with the french fries. Toss to combine. Adjust seasoning with salt and pepper. Garnish with chopped cilantro and serve with aji sauce and rice.
Notes
You can use fresh potatoes instead of frozen fries.The aji sauce can be prepared up to 2 days in advance.
