Creating Turkey and Swiss Cheese Sliders can be a delightful experience if you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C).
2. Prepare the Baking Dish: Grease a 9×13-inch baking dish or line it with parchment paper for easy removal.
3. Assemble the Sliders: Slice the slider buns in half horizontally and layer the bottom halves in the prepared baking dish.
4. Add Turkey: Layer the turkey slices evenly over the bottom buns.
5. Layer Swiss Cheese: Place a slice of Swiss cheese on top of the turkey.
6. Prepare the Sauce: In a small bowl, mix the melted butter, Dijon mustard, Worcestershire sauce, garlic powder, onion powder, poppy seeds, salt, and pepper until well combined.
7. Brush the Sauce: Drizzle or brush the sauce mixture generously over the Swiss cheese layer.
8. Top with Buns: Place the top halves of the slider buns over the cheese and sauce.
9. Bake: Cover the baking dish with foil and bake for 15 minutes. Then, remove the foil and bake for an additional 5-10 minutes, or until the tops are golden and crispy.
10. Serve: Remove from the oven and let cool slightly. Slice between the sliders to separate and serve warm.
