Preheat oven to 350 degrees.

Combine the breadcrumbs and milk in a large mixing bowl. Let stand for about 5-10 minutes until the breadcrumbs are soggy.

Add the remaining ingredients to the bowl. Mix together until everything is thoroughly combined. You can use a spoon, but I think the best way to mix meatball ingredients without overmixing is to use your hands.

Prepare a baking sheet with cooking spray. Roll the meat mixture into approximately 1 ½ - inch balls. Arrange the meatballs on the baking sheet. You don’t have to worry about them spreading, but you also don’t want them touching.

Arrange the formed meatballs on a cooking tray. Place the cooking tray with the uncooked meatballs on a flat surface in the freezer. Allow meatballs to freeze completely, then place them in a freezer safe container or plastic bag. When you are ready to cook them, only pull out as many as you need.
