How to Make It
Bring a large pot of salted water to a boil. Heat 2 teaspoons of the oil in a large skillet over medium-high heat. Season the steaks with ½ teaspoon salt and ¼ teaspoon black pepper and cook to the desired doneness, 4 to 6 minutes per side for medium-rare. Let rest for at least 5 minutes before slicing.
Wipe out the skillet and heat 1 teaspoon of the remaining oil over medium-high heat. Add the tomatoes and ¼ teaspoon each salt and black pepper. Cook, tossing occasionally, until beginning to soften, 4 to 6 minutes. Mix in the oregano.
Meanwhile, cook the green beans in the boiling water until tender, 3 to 4 minutes; drain. Wipe out the pot and heat the garlic in the remaining 3 tablespoons of oil over medium heat, stirring frequently, until fragrant, 1 to 2 minutes. Add the green beans, ½ teaspoon salt, and ¼ teaspoon black pepper and toss to combine. Sprinkle with the red pepper and serve with the steak and tomatoes.
