Step 1
Mix 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 3
Cover 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 4
Let 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.
