Pepper-Crusted Beef, Bacon, and Arugula Sandwiches with Spicy Mustard

Preparation

1. Step 1

   Coat steaks all over with pepper. Mix mayonnaise, mustard, and horseradish in small bowl for dressing. Cover steaks and dressing separately and refrigerate at least 30 minutes and up to 1 day.

   Step 2

   Toss thinly sliced mushrooms and lemon juice in medium bowl to coat evenly. Sprinkle lightly with salt. Brush heavy large skillet generously with oil and heat over medium-high heat. Add steaks and cook to desired doneness, about 5 minutes per side for medium-rare. Transfer steaks to plate; let stand 15 minutes. Cook bacon in same skillet over medium-high heat until brown and crisp. Using tongs, transfer bacon to paper towels to drain.

   Step 3

   Place roll bottoms on plates; spread with dressing. Slice steaks thinly and divide among rolls. Top with bacon, mushrooms, and arugula. Cover sandwiches with roll tops and serve.
