Wash parsley and shake dry, pluck off the leaves. Cut the pecorino into 24 pieces. Cut the steaks in half, beat flat and season with pepper. Cover each steak with 1 slice of pancetta, 1 piece of pecorino and 1 parsley leaf.
Roll up each piece to a small ball and fix it with 1 wooden skewer. Season with salt. Distribute on the grill trays. Grill on the hot grill for 3-4 minutes while turning. Serve with lemon wedges to drizzle on.
Ciabatta is delicious with it.
