Ham and Cheese Sliders

Steps

1. Preheat the oven to 350°F (175°C) and set an oven rack in the middle position.

2. In a small bowl, whisk together all of the ingredients for the butter sauce. Set aside.

3. Using a serrated bread knife, slice the rolls in half horizontally, keeping the top and bottom halves separately intact. (Don't worry if the rolls fall apart; you can piece them back together in the pan.) Spread the Dijon mustard evenly over the cut sides of the roll tops and bottoms.

4. Place the bottom half of the bread, cut side up, in a 9-in (23-cm) square baking pan. Place half of the cheese in an even layer over the bread. Top with all of the ham, followed by the remaining cheese. Cover with the roll tops.

5. Evenly spoon the butter sauce over the top of the rolls, letting it drip down the sides.

6. Bake for 22 to 25 minutes, until the top is golden brown and toasted. Let cool for 15 to 20 minutes in the pan. Using a large spatula, carefully transfer the sandwich block to a cutting board. Slice into sandwiches and transfer to a serving plate. Serve warm or at room temperature.
