1Season the steak with the basil, oregano, 1/2 teaspoon of the salt, and the pepper. Combine the tomatoes, olives, shallots, parsley, vinegar, extra-virgin olive oil, and remaining 1/4 teaspoon salt in a medium bowl.
2Lightly dampen a paper towel with a small amount of olive oil and wipe a grill pan with it; heat over medium-high heat. Add the steaks and cook until the beef is cooked to medium-rare, 5 to 6 minutes per side or longer to your desired doneness. Serve topped with the tomato mixture.
