Place the buns on a flat surface and slice the buns all together.
Put the bottom part of the buns in a 9x13 aluminum baking tray.
Layer cheddar cheese, roasted turkey, honey ham, and then the Swiss cheese on top of the buns and then replace the top layer of the buns.
Brush the melted butter over top of the buns.
Cover the tray with a layer of plastic wrap and two layers of aluminum foil and store in the freezer until you’re ready to eat.
Thaw overnight in the fridge.
Remove the plastic wrap and replace the foil.
Preheat the oven to 350°F and bake for 20 minutes.
Remove the foil and bake for an additional 5 minutes until the buns are toasted and the cheese is melted.
Slice the buns to cut the sliders.
Pull the sandwiches apart out of the tray and serve.
