Preheat oven to 350ºF. Spray 9x13 baking dish with cooking spray.
Slice Hawaiian rolls in half lengthwise and place the bottom half into the baking dish.
Layer the deli turkey across the rolls.
Spread the cranberry sauce evenly across the top of the turkey.
Add 6 slices of havarti or provolone cheese in an even layer.
Place the top bun layer onto the sliders.
Mix together the melted butter, Worcestershire, Dijon mustard, minced dried onion, poppy seeds and chives in a small bowl. Generously brush across the tops of the slider buns.
Cover the baking dish with foil and bake in the oven for 15-18 minutes, or until the sliders are warmed through and the cheese is melted.
Remove foil and bake for another 3-5 minutes to brown the tops of the sliders.
Serve immediately.
