HERB SAUCE FOR STEAK RECIPES

Steps:

• Prepare outdoor grill for direct grilling on medium-high. Fit wire rack into jelly-roll pan. Prepare herb sauce: In food processor with knife blade attached, combine parsley, cilantro, and garlic; pulse until finely chopped. Add oil, vinegar, oregano, red pepper, and 1/8 teaspoon each salt and black pepper; pulse to blend. Pat steaks dry. Sprinkle 1/2 teaspoon each salt and pepper all over steaks. Immediately place on grill; cook 7 to 8 minutes for medium-rare or until desired doneness, turning over every 2 to 3 minutes. Transfer to wire rack. Let stand 5 minutes. Stir any meat juices into herb sauce. Slice steak; serve with sauce.

Steps:

• Heat a 12-inch cast-iron skillet over medium-high. Add 1 tablespoon of the oil to skillet, and swirl to coat. Sprinkle both sides of steak evenly with 1½ teaspoons of the salt and 1 teaspoon of the pepper. Cook steak in hot skillet, flipping about every 2 minutes, until a thermometer inserted in thickest portion of meat registers 125°F (for medium-rare), 5 to 7 minutes. Transfer steak to a cutting board; cover loosely with aluminum foil, and let rest 10 minutes. 
• While steak rests, pulse parsley, cilantro, shallot, vinegar, garlic, and remaining ½ teaspoon each salt and pepper in a food processor until finely chopped, about 10 pulses, stopping to scrape down sides as needed. With processor running, slowly pour remaining ½ cup oil through food chute until mixture is thoroughly combined but still chunky, about 10 seconds. 
• Cut steak diagonally against the grain into ¼-inch-thick slices, and arrange on a platter. Serve with roasted potatoes and herb sauce.
