Preheat your oven to 350°F (175°C). Take your Hawaiian rolls out of the package and place them on a cutting board or flat surface. Using your serrated knife, slice the rolls horizontally, cutting the entire top half of the rolls off in one whole section, and place them aside.
Spread a generous layer of mayonnaise on the bottom half of the rolls and place them into an ungreased baking dish. Next, spread the shaved turkey on the rolls, then spread the cranberry sauce, then the stuffing. Sprinkle with a pinch of salt and pepper.
Spread another generous layer of mayonnaise on the top half ot the rolls and place them on the assembled sliders.
With your hand on the rolls, apply pressure as you cut along the lines with a serrated knife, making them easier to pull apart after baking.
Brush tops with melted butter or spray with olive oil spray. Sprinkle with poppyseeds if using.
Cover with aluminum foil and bake on the middle rack of your oven for about 20-25 minutes, or until the tops are golden and the sliders are warmed throughout.
Serve and enjoy!
