Argentinian Beef Steak with Tomato and Onion Sauce

1Season the beef steak with salt, pepper, and a touch of olive oil. Set aside for 10 minutes to marinate.

2In a skillet, heat olive oil over medium heat. Add the seasoned beef steak and cook to desired doneness (about 5-7 minutes per side for medium rare). Remove from the skillet and let it rest.

3In the same skillet, add more olive oil if needed. Sauté the chopped onion until translucent, then add minced garlic and sliced ají. Cook for 2-3 minutes until fragrant.

4Add diced tomatoes to the skillet and simmer for 5-7 minutes until the tomatoes are softened.

5Return the beef steak to the skillet and simmer in the tomato and onion sauce for an additional 2-3 minutes to absorb the flavors.

6In a separate pan, heat oil for frying. Slice the plantains and fry until golden brown and crispy on both sides. Drain on paper towels to remove excess oil.

7Serve the Argentinian beef steak with the tomato and onion sauce drizzled on top, accompanied by the crispy fried plantains.

8Enjoy this delicious and traditional Argentinian dish!
