Preheat your oven to 400°F (200°C).
In a large bowl, combine ground beef, ground pork, breadcrumbs, and Parmesan cheese.
Add chopped parsley, egg, minced garlic, salt, and pepper to the meat mixture.
Mix all ingredients until well combined.
Form the mixture into small meatballs, about 1 inch in diameter.
Place the meatballs on a baking sheet lined with parchment paper.
Bake in the preheated oven for 20-25 minutes.
While the meatballs bake, heat the barbecue sauce in a saucepan over medium heat.
Once the meatballs are done, transfer them to the saucepan and coat them in the sauce.
Serve warm with toothpicks for easy eating.
