Creating these delicious Ham Cheese Pretzel Sliders is a breeze when you follow these simple steps:

1. Preheat the Oven: Begin by preheating your oven to 350°F (175°C).
2. Prepare the Sliders: Slice the pretzel buns in half horizontally without separating them completely. Place the bottom half in a baking dish.
3. Layer the Ham and Cheese: On the bottom half of the buns, layer the sliced ham evenly, followed by a layer of cheese.
4. Cover with the Top Buns: Place the top half of the pretzel buns back on top of the ham and cheese layers.
5. Make the Butter Mixture: In a small bowl, mix the melted butter, Dijon mustard, brown sugar, garlic powder, onion powder, and coarse sea salt until well combined.
6. Brush the Sliders: Generously brush the butter mixture over the top of the pretzel buns.
7. Add Sesame Seeds: If desired, sprinkle sesame seeds on top for added flavor and texture.
8. Bake: Place the baking dish in the preheated oven and bake for 15-25 minutes or until the cheese is melted and the tops are golden brown.
9. Serve Warm: Remove from the oven and let cool slightly before slicing into individual sliders.

These steps will guide you in creating these incredible Ham Cheese Pretzel Sliders effortlessly.
