Preheat the oven to 350 F. Spray 9x13 baking dish with cooking spray.
Slice the rolls in half lengthwise and place the bottom half into the baking dish.
Layer the deli turkey across the rolls.
Next spread the cranberry sauce over the turkey and top with the cheese slices (you’ll need to tear or cut the slices in half).
Place the top bun layer onto the sliders.
Make the butter sauce:
In a small bowl, mix together the melted butter Worcestershire Sauce, mustard, dried onion, and poppy seeds. Generously brush across the tops of the buns.
Cover the 9x13 pan with foil and bake for 15 minutes. Remove the foil and bake for another 5-10 minutes or until the top is brown.
