Step 1
Preheat the oven to 350°F. Grease a 9x13-inch baking dish with cooking spray or line with aluminum foil or parchment paper.

Keeping the rolls intact, use a sharp serrated knife to slice the rolls in half horizontally so the tops and the bottoms of the rolls are separated into two large pieces.

Step 3
In a small bowl, combine the mayonnaise and horseradish. Place the bottom piece of the rolls in the pan and spread with the mayo mixture.

Step 4
Top the mayo mixture with 6 slices of the cheese, roast beef and then the remaining 6 slices of cheese. Bake for 10 minutes in the preheated oven, allowing the cheese to melt.

Step 5
Meanwhile, in a small bowl, combine the melted butter, dijon mustard, onion powder, garlic powder, and the poppy seeds.

Step 6
Remove the rolls from the oven and top with the roll top piece. Pour the butter mixture over the tops, cover with aluminum foil and bake for 10 minutes. Remove the foil and bake for an additional 10 minutes, or until golden brown. Serve and enjoy!
