Start by soaking the breadcrumbs in the milk for about 20 minutes.
Then in a large mixing bowl, add the ground pork, ground beef, eggs, bread crumb mixture, onion powder, Parmesan cheese, brown sugar, garlic powder, onion powder, salt, chili powder, smoked paprika, ground cumin, and black pepper.
Then roll the meatball mix into desired meatball size.
As you make them place them into the air fryer basket, being careful not to crowd the basket.
Set the temperature to 400 degrees F, for 12-15 minutes.
While the meatballs are air frying, in a small mixing bowl, mix together the sauce ingredients.
