To make tantalizing Halloween Chicken Parmesan Sliders, follow these straightforward steps:

1. Preheat the Oven: Begin by preheating your oven to 375°F (190°C).
2. Prepare Chicken: Slice the chicken breasts into smaller pieces suitable for sliders.
3. Season Flour: In a shallow dish, mix the flour with garlic powder, Italian seasoning, salt, and pepper.
4. Dredge Chicken: Dip each piece of chicken into the seasoned flour, then into the beaten eggs, and finally coat it with breadcrumbs.
5. Arrange on a Baking Sheet: Place the breaded chicken on a baking sheet lined with parchment paper.
6. Drizzle with Olive Oil: Lightly drizzle olive oil over the chicken for added crispiness.
7. Bake the Chicken: Place the baking sheet in the oven and cook for 20 minutes or until the chicken is golden brown and cooked through.
8. Heat Marinara Sauce: While the chicken is baking, gently heat the marinara sauce in a small saucepan over medium heat.
9. Assemble Sliders: Once the chicken is cooked, take a slider bun and place a piece of chicken on the bottom half. Spoon marinara sauce over the chicken and sprinkle with mozzarella cheese.
10. Melt Cheese: Return the assembled sliders to the oven for another 5-7 minutes or until the cheese is bubbly and golden.
11. Garnish: Optionally, top with fresh basil leaves for a touch of color and flavor.
12. Serve: Once the cheese is melted, remove from the oven and place the top buns on each slider.
