01 - Preheat the oven to 350°F (175°C).
02 - Slice the slider rolls in half horizontally, keeping individual rolls attached. Arrange the bottom halves in a lightly greased 9x13-inch baking dish.
03 - In a small bowl, combine mayonnaise and Dijon mustard. Spread the mixture evenly over the cut side of the bottom rolls.
04 - Distribute the turkey evenly over the prepared buns. Spoon cranberry sauce over the turkey.
05 - Layer halved slices of cheese over the turkey and cranberry. Place the top halves of the rolls over the cheese.
06 - In another small bowl, mix melted butter with garlic powder, onion powder, poppy seeds, and parsley. Brush the mixture generously over the tops of the rolls.
07 - Cover the baking dish with foil and bake for 15 minutes. Remove foil and continue baking for an additional 5 minutes, until cheese is melted and tops are golden.
08 - Remove from oven, cool briefly, then separate the sliders using a sharp knife. Serve warm.
