• 1 pound boneless beef, eye round
• 1/2 tablespoon kosher salt
• 1 tablespoon coarsely ground black pepper
• 1/2 pound daikon radish, peeled and julienned or shredded
• 1 1/2 tablespoons white wine vinegar
• 1 teaspoon kosher salt
• 1 teaspoon sugar
• 1 tablespoon extra-virgin olive oil
• 1 tablespoon prepared horseradish
• 1/2 tablespoon chopped flat-leaf parsley
• Freshly ground black pepper
• 4 ciabatta rolls
• 4 tablespoons Mayonnaise (page 176), made with beef drippings instead of water
• 1/2 cup Grilled Red Onions (page 190)
• 4 small radishes, thinly sliced

1. Preheat the oven to 325F.
2. To make the roast beef, pat the meat dry and rub with the salt and pepper.
3. In a hot ovenproof skillet, sear the meat until browned all over.
4. Transfer to the oven and roast for about 30 minutes, until it reaches an internal temperature of 120F.
5. Remove the meat from the oven and transfer to a plate.
6. Set aside to rest and cool completely, ideally overnight.
7. Collect any juices from the skillet, and reserve 1 to 2 tablespoons for the mayonnaise.
8. If needed, add some water to the skillet, stir, and reserve additional juices.
9. To make the radish slaw, in a medium bowl, toss the daikon radish in the vinegar, salt, and sugar and marinate at room temperature for 1 hour.
10. Place the daikon in a strainer and drain for 30 minutes.
11. Transfer to a bowl and toss in the oil, horseradish, parsley, and pepper.
12. Cut the ciabatta rolls in half and thinly slice the roast beef.
13. Spread the mayonnaise on the bottom halves and top with the roast beef, onions, radish slaw, and sliced radishes.
14. Close the sandwiches, cut into halves, and serve.
