Preheat the oven to 400°F (200°C). Line a baking sheet with parchment paper.
In a large mixing bowl, combine ground pork, ground beef, breadcrumbs, egg, Italian herbs, garlic, onions, Worcestershire sauce, salt, and black pepper.
Mix everything together using hands or a spoon until well combined.
Roll the mixture into small balls, about 1 inch in diameter.
Place the meatballs on the prepared baking sheet, spacing them evenly.
Bake for 15 to 20 minutes, until the centers reach 160°F (71°C).
Let the mini meatballs cool for a few minutes before serving.
