Follow these steps to create your Ham Egg and Cheese Breakfast Sliders effortlessly:

1. Preheat Oven: Preheat your oven to 350°F (175°C).
2. Prepare the Baking Dish: Grease a 9×13-inch baking dish with non-stick spray or butter.
3. Slice the Buns: Cut the slider buns in half horizontally, keeping the tops and bottoms connected. Place the bottom halves in the prepared baking dish.
4. Layer the Ham: Evenly distribute the sliced ham over the bottom half of the buns.
5. Whisk the Eggs: In a bowl, whisk together the eggs, adding garlic powder, onion powder, salt, and pepper to taste. If using, mix in the Dijon mustard.
6. Scramble the Eggs: In a skillet over medium heat, melt the butter. Pour in the egg mixture and cook, stirring occasionally, until just set but still soft. Remove from heat.
7. Add Eggs and Cheese: Pour the scrambled eggs over the ham on the buns. Sprinkle the shredded cheese on top.
8. Cover with Top Buns: Place the top halves of the slider buns onto the cheese.
9. Bake: Cover the baking dish with foil and bake for 15 minutes. Remove the foil and bake for an additional 10 minutes, or until the cheese is melted and the tops are golden.
10. Cool and Serve: Allow the sliders to cool for a few minutes before slicing apart. Garnish with fresh herbs if desired.
