Ingredients

• 4 beef fillet medallions, (about 6 to 8 ounces each)
• Olive oil, for brushing
• 2 teaspoons kosher salt
• Freshly ground black pepper
• 3 shallots, sliced
• 2 cloves garlic
• 1/4 cup white wine vinegar
• 1 cup fresh flat-leaf parsley leaves
• 1/2 cup fresh cilantro leaves
• 1/4 cup chopped chives
• 1/4 cup fresh tarragon leaves
• 3/4 cup extra-virgin olive oil, plus more for brushing steak
• 1 1/4 teaspoons kosher salt
• Freshly ground black pepper

Instructions

1. A half-hour before cooking, remove the medallions from refrigerator.
2. Sauce: Put the shallots, garlic, vinegar, and all the herbs in a food processor and pulse until herbs are minced, with the motor running slowly drizzle in the olive oil until you have a thick sauce. Season with salt and pepper and the sauce is ready to serve.
3. Prepare a grill or a stove top grill pan with a medium-high heat fire.
4. Brush meat lightly with olive oil and season with salt and pepper. Place medallions on the grill and cook, without moving, until nice grill marks appear, about 4 minutes. Turn the medallions and continue to grill until an instant-read thermometer inserted into the medallions sideways registers about 120 degrees F, about 3 to 4 minutes more. Set aside on a cutting board to rest for 5 minutes before serving.
5. Divide medallions among plates and drizzle with some of the sauce. Serve. Pass the remaining sauce at the table.
