Creating Mississippi Sin Ham Sliders is a straightforward process. Follow these simple steps for a delicious outcome:

1. Preheat the Oven: Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish.
2. Prepare the Sauce: In a mixing bowl, combine the cream cheese, mayonnaise, Dijon mustard, Worcestershire sauce, garlic powder, onion powder, and black pepper. Mix until smooth and well combined.
3. Assemble the Sliders: Cut the slider buns in half horizontally. Spread a layer of the cream cheese mixture on the bottom half of each bun.
4. Add the Ham and Cheese: Layer the sliced ham evenly over the cream cheese mixture. Sprinkle the shredded cheddar and mozzarella cheese on top of the ham.
5. Top with Buns: Place the top halves of the slider buns over the cheese layer.
6. Brush with Butter: In a separate bowl, mix the melted butter with poppy seeds (if using). Brush the mixture generously over the top of the slider buns.
7. Bake: Cover the baking dish with aluminum foil and bake in the preheated oven for 15 minutes. Then, remove the foil and bake for an additional 10-15 minutes, or until the sliders are golden brown and the cheese is melted.
8. Cool and Slice: Once baked, remove from the oven and allow the sliders to cool for a few minutes. Slice into individual sliders to serve.

These steps will guide you in creating these incredible sliders effortlessly.
