Step 1Mix together the olive oil, vinegar, garlic, rosemary, oregano, salt, and pepper. Marinate the steak in this mixture for at least 1 hour up to 24 hours.
Step 3Cover a broiler pan with foil. Remove the steak from marinade, letting excess drip off. Place the steak in the middle of the rack and cook for 4-6 minutes per side for medium. When you flip the steak, add the tomatoes to the pan as well. To grill: Grill the steak for 4-6 minutes per side for medium. When you flip the steak, add the tomatoes directly to the grill or in a grill basket and cook until warmed and beginning to char.
Step 4Let the steak rest for five minutes before serving. Slice against the grain into thin strips. Roughly chop the tomatoes and toss with basil. Serve with the steak.
