In a small bowl, add the two slices of bread and cover with the milk. Let the bread absorb all of the milk, then gently using your hands, break apart the bread and set aside.
In a large mixing bowl, add in the meat, parsley, parmesan, garlic, salt, pepper, and milk soaked bread. Gently mix the ingredients together using your hand.
Add in the egg and mix again to incorporate.
Form into small balls, about the size of a golf ball. You can make them smaller or larger if desired, but you will need to adjust the cooking time slightly.
If baking immediately, place onto a foil lined baking sheet and bake at 375F for about 20 minutes.
Serve with your favorite marinara sauce or add into pasta sauce making spaghetti and meatballs. If adding to soups, you can add them in uncooked and let them cook in the broth.
