Italian Grilled Steak Sandwich

Directions

1. Place first 4 ingredients in a large bowl or shallow dish. Add steak and turn to coat. Refrigerate, covered, 8 hours or overnight.
2. Remove steak, discarding marinade. Grill steak, covered, over medium heat or broil 4 in. from heat until meat reaches desired doneness (for medium-rare, a thermometer should read 135°; medium, 140°), 6-8 minutes per side. Cool completely.
3. Cut bread loaf horizontally in half. Hollow out both halves, leaving a 1/2-in. shell (save removed bread for another use). Cut steak across the grain into thin slices. In a bowl, toss tomatoes with green onions, olives, pepperoni, basil and 2 tablespoons dressing. In another bowl, toss arugula with remaining 1/4 cup dressing.
4. Place half the arugula in bread bottom. Layer with steak, tomato mixture and remaining arugula; replace top. Wrap in foil; refrigerate at least 1 hour. Cut into wedges to serve.
