Steak and Arugula Sandwiches

Preheat the grill to medium. Season the steaks with salt and pepper. Grill to desired doneness, about 6 minutes per side for rare. Remove from the grill and allow to rest for 5 minutes. Thinly slice the steaks and set aside. In a small bowl, toss the arugula with olive oil; season with salt and pepper. Slice the rolls and remove some of the soft bread inside to make a shallow well in each piece. Spread the cheese on both sides of the bread. On the bottom layer, place tomato slices and top with the sliced steak and arugula. Add the top half of the bread and press together gently. Serves 4.
