In a medium mixing bowl, combine ground chicken, Parmesan cheese, breadcrumbs, 1/4 cup marinara sauce, onion, garlic, parsley, salt, and black pepper. Mix the ingredients evenly.
2
Divide the mixture into 4 equal portions, and shape them into patties.
3
Heat olive oil in a large skillet over medium-high heat.
4
Place the patties in the skillet and cook for 4-5 minutes or until golden brown on one side.
5
Flip the patties and pour the remaining marinara sauce around them.
6
Bring the sauce to a simmer, reducing the heat if it bubbles too rapidly.
7
Top each patty with an equal amount of shredded mozzarella cheese, then cover the skillet and cook for 8-10 minutes, or until the cheese melts and the slider is cooked through.
8
Spoon some marinara sauce onto the bottom halves of the hamburger buns; then, place the cooked chicken patties on top.

Place the top halves of the buns over the patties and serve immediately.
