Place cranberries, sugar, orange juice, and water in a small saucepan over medium heat. Bring to a boil, then simmer for 10 minutes. The cranberries will burst during cooking. Remove from heat and let cool for 5 minutes.
Place cranberry mixture into a Magic Bullet blender and pulse for 15-30 seconds. Place the sauce in a small sieve and press through to remove the seeds and skins. Place in refrigerator until ready to use.
Preheat oven to 375 degrees. Spray the glass dish and the underside of the lid with cooking spray. Set aside.
Slice the rolls in half, keeping the pieces together if possible. Lay the bottom of the rolls in the prepared dish. Place the whole slice of Swiss cheese, all the ham, and the whole slice of Mozzarella on the roll bottoms.
Place 1/2 Tbsp of the cranberry sauce on top of the mozzarella cheese. Lastly, place the top of the rolls on sliders.
Spread/ pour the melted butter on top of the rolls and sprinkle with the poppy seeds.
Place the lid on the dish and bake for 20 minutes or until the cheeses melt. Remove the lid, cook for an additional 5 minutes. Remove from the oven and cut along roll seams to make four sliders.
Serve immediately. Serve sliders with the remaining cranberry sauce as a dip.
