Easy Delicious Rueben Sliders

Preheat the oven to 350 degrees.

Make spread by whisking together mayonnaise, ketchup, horseradish, Worcestershire, and salt and pepper to taste. Set aside.

Take the lid off the buns but don't separate them. Place the bottom buns on parchment paper on a cookie sheet.

Spread sauce on the top and bottom buns. On the bottom bun, add a layer of cheese, corned beef, the sauerkraut (you may not use the entire can), then another layer of cheese, top with the top bun.

Brush the tops of sandwiches with butter and sprinkle with poppy seeds.

Bake at 350 for 10-12 minutes or until the cheese is melted and sandwiches are heated through.
