This pesto made with parsley and sharp Pecorino Romano cheese makes a colorful topping for tender lamb chops. It could also be tossed with pasta, spread on sandwiches, or mixed with cream cheese for a dip to serve with crudités.
In a food processor, finely chop parsley, cheese, and garlic. With the motor running, add oil in a slow, steady stream; season with pepper. Serve immediately, or transfer to an airtight container and cover with a thin layer of oil; refrigerate up to 4 days or freeze up to 3 months. Makes 1/2 cup.
Heat a large skillet over medium. Pat dry lamb with paper towels. Season chops on both sides with salt and pepper. Cook (in two batches, if necessary) 4 to 6 minutes per side for medium-rare. Serve immediately, topped with pesto.
