Directions:

Preheat grill to medium high and place a cast iron pan or grill vegetable basket on the grill. Season sirloin steak with 1 teaspoon salt and 1/2 teaspoon pepper. Toss tomatoes with 2 tablespoons olive oil, season with salt and pepper to taste.

Place tomatoes in hot pan, stirring occasionally, until soft and beginning to blister, about 2 minutes; remove and set aside.

Grill steak in cast iron or directly on grate to desired doneness (125 degrees - 130 degrees F for medium rare). Remove from grill and let rest.

Reduce grill temperature to medium. Brush rolls on both sides with remaining olive oil and crisp on grill, 1 minute per side.

Slice steak thinly against the grain.

Spread rolls with olive tapenade and top with blistered tomatoes, steak, frisee and parmesan. If desired, drizzle lightly with additional olive oil and season with salt and pepper. Slice and serve.
