In a bowl, combine all the ingredients for the meatballs except the breadcrumbs, pork, beef, and neutral oil. Whisk to combine. Taste and season to your preferences with salt, pepper, and crushed red pepper.
Add the breadcrumbs to the mixture and stir to combine. Let stand for 5 minutes to allow the breadcrumbs to absorb the liquid.
Add the pork and beef and season the meat with salt, pepper, and crushed red pepper.
Using your hands, gently mix to combine everything. Do not over-mix the meat.
Form the meat into tablespoon-sized meatballs and transfer to a plate.
