Creating the Pierogi and Meatball Skillet is straightforward when you follow these steps:

1. Preheat Skillet: Heat olive oil in a large skillet over medium heat.
2. Prepare Meatballs: In a mixing bowl, combine ground beef (or turkey), breadcrumbs, egg, garlic powder, onion powder, salt, and black pepper. Mix well until fully combined.
3. Form Meatballs: Use your hands to shape the mixture into small meatballs, about 1 inch in diameter.
4. Brown Meatballs: Place the meatballs in the heated skillet and cook for about 5–7 minutes, turning occasionally until browned on all sides.
5. Add Pierogi: Once the meatballs are browned, add the frozen pierogi directly into the skillet.
6. Pour Sauce: Pour the marinara sauce over the meatballs and pierogi, ensuring they are well coated.
7. Simmer: Reduce heat to low, cover the skillet, and let it simmer for about 15 minutes until the pierogi are heated through.
8. Add Cheese: Sprinkle the shredded mozzarella cheese over the top, cover again, and allow the cheese to melt for about 5 minutes.
9. Garnish and Serve: Once the cheese is melted and bubbly, sprinkle with chopped fresh parsley for garnish before serving.
