Creating Baked Club Sliders is simple if you follow these steps:

1. Preheat the Oven: Set 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. Mix the Spread: In a small bowl, combine mayonnaise and Dijon mustard. Mix until well blended.
4. Assemble the Bottom Layer: Place the slider buns in the baking dish. Spread half of the mayonnaise mixture on the bottom half of the buns.
5. Add the Meats: Layer the turkey slices evenly over the sauce, followed by the ham and crumbled bacon.
6. Layer the Cheese: Place a slice of Swiss cheese on top of the meat layers.
7. Top with Vegetables: If desired, add fresh lettuce and sliced tomatoes for extra crunch.
8. Cover with Buns: Place the top halves of the slider buns on the assembled layers.
9. Brush with Butter: Drizzle the melted butter over the top of the buns and sprinkle with poppy seeds. Season with salt and pepper to taste.
10. Bake: Place the dish in the preheated oven and bake for 25-30 minutes, or until the cheese is melted and the buns are golden brown.
11. Slice and Serve: Remove from the oven and let cool for a few minutes before slicing into individual sliders.
