Whisk the olive oil, vinegar, garlic, rosemary, parsley, oregano, honey, red pepper flakes, and 1/2 teaspoon each salt and pepper in a medium bowl. Reserve 3 tablespoons of the marinade in a small bowl. Cover and refrigerate until ready to serve.
Combine the remaining marinade with the steak in a large resealable bag. Turn the bag several times to coat the meat. Refrigerate at least 4 hours or overnight, turning the bag occasionally.
Preheat a grill or grill pan to high. Transfer the steak to a plate or baking sheet, letting the excess marinade drip off. Season the steak with salt and pepper. If possible, let stand at room temperature for 30 minutes.
Grill the steak until a thermometer inserted into the thickest side reaches 130 degrees F. For a 1 1/2 to 2 inch steak, this is about 16 to 20 minutes for medium rare, flipping every 4 to 5 minutes. Transfer the meat to a cutting board and let it rest 10 minutes. Serve whole or slice the meat to your preferred thickness, against the grain. Serve with the reserved marinade.
