In a small bowl add the bread crumbs and milk.
Let sit for a couple minutes until the milk is absorbed by the bread crumbs.
In a very large bowl, add the ground beef, the bread crumb mixture, eggs, Parmesan cheese, herbs, garlic and minced onion. Mix together until fully incorporated.
Using a spring ice cream or cookie scoop, scoop meatball mixture and place on a parchment sheet. Roll out meatballs.
Put meatballs into the hot sauce.
Cook approx 1 hour or until an instant read thermometer reads 160 to 165 degrees F.
These meatballs are soft so be very careful taking them out of the sauce.
