Mix the oil, garlic, herbs, salt, and pepper in a small bowl. Rub all over the steak and let sit for about 20 min. at room temperature. Meanwhile, heat a gas grill to medium-high (you should be able to hold your hand 2 inches above the grate for 3 to 4 seconds) or prepare a medium-hot charcoal fire. If your grill has a hot spot, position the thicker end of the flank steak nearer the hottest part of the fire. Grill until medium rare, 12 to 15 min., turning the steak every 3 to 4 min. to ensure even cooking. The thickest part of the steak will register 135°F to 140°F on an instant-read thermometer. Transfer the steak to a cutting board and let it rest for 3 to 5 min. Slice across the grain, portion onto dinner plates, spoon on the vinaigrette, and serve.
Pour a light, fruity Côtes du Rhône blend, or a Grenache-based rosé.
