Cut the slider rolls in half horizontally, keeping the individual rolls attached.
Place the bottom half of the rolls in a greased baking pan. Top the rolls with the cheese, turkey, and stuffing. Divide evenly between the rolls as much as possible. Place the top of the rolls on top of the stuffing.
In a small bowl, mix together the melted butter, garlic powder, dijon mustard, and Worcestershire Sauce. Use a pastry brush to evenly brush the tops of the sliders with the garlic butter sauce.
Optional topping: sprinkle sea salt over the top of the rolls.
Cover with aluminum foil and bake for 20 minutes. Remove the foil and bake for another 8-9 minutes or until warm throughout. Keep an eye on them to ensure the rolls don't burn. Sprinkle parmesan cheese on top and bake for 1 additional minute.
While the sliders are baking, make a batch of turkey gravy or heat up store bought gravy.
Let the sliders rest for 5 minutes. Right before serving remove the top of the sliders and sprinkle fried onions over the stuffing. Place the top back on and serve with hot turkey gravy for dipping.
Notes
Note 1 - If you have leftover dinner rolls from your holiday meal, this is a great way to use them up. Note 2 - Leftover turkey, freshly baked turkey, or sliced deli meat can be used. Note 3 - Don't go crazy. Just a few pinches spread over the top is perfect. Don't replace with any other kind of salt.Note 4 - Store bought gravy works just as well as homemade gravy.
