Prepare the Baking Dish

• Preheat oven to 325°F.
• Line a 9×13-inch baking dish with foil, ensuring enough overhang to use as handles for easy lifting.
• Lightly coat the foil-lined dish with cooking spray.

Assemble the Sliders

• Keeping the rolls connected, slice them horizontally as one unit. Do not separate into individual rolls.
• Place the bottom half of the rolls into the prepared baking dish.
• Layer the ham, turkey, and grated Gruyère cheese evenly over the rolls.

Make the Sauce

• In a small bowl, whisk together the melted butter, beaten egg, Worcestershire sauce, Dijon mustard, and mayonnaise until smooth.
• Pour half of the sauce evenly over the layered cheese and meats.

Bake the Sliders

• Place the top half of the rolls over the assembled ingredients, pressing down lightly.
• Pour the remaining sauce over the tops, brushing to distribute evenly.
• Bake uncovered for 25-30 minutes.
• If the tops brown too quickly, cover loosely with foil to prevent burning.

Finish & Serve

• Remove from oven and allow to cool for about 15 minutes.
• Using the foil handles, carefully lift the entire slab of sliders onto a cutting board.
• Cut into individual sliders with a sharp knife.
• Dust generously with powdered sugar.

••Serve warm with raspberry preserves on the side for dipping.
