Line a large rimmed baking sheet with foil and coat the foil with nonstick cooking spray. Set it aside.
In a large bowl, mash the bread and milk together with a fork until it forms a thick paste. Add the salt, pepper, Worcestershire sauce, onion and garlic and stir to combine. Crumble the beef and sausage over the mixture then add the remaining meatball ingredients. Gently combine with a wooden spoon, then work with your hands, just until combined.
Using a large cookie scoop or a 1 tablespoon measuring spoon, scoop about 2 tablespoons of meatball mixture and use your hands to form it into a neat ball. Set the meatball down on the prepared baking sheet and repeat to form the remaining meatballs. Rinse your hands with water, as needed throughout the process to prevent the meatball mixture from sticking.
With a rack set in the top one-third of the oven, turn the oven to BROIL. Transfer the baking sheet to the oven and broil for about 3 minutes, or until the tops of the meatballs are nicely browned. Remove the baking sheet from the oven and use kitchen tongs to flip the meatballs. Return them to the oven for an additional 2 to 3 minutes to brown the other side. Remove from the oven.
Pour the pasta sauce into a Dutch oven and set over MEDIUM-LOW heat. Add the meatballs and bring the mixture to a low simmer. Reduce heat to LOW and simmer for about 10 to 15 minutes, or until the sauce is warmed and the meatballs are cooked through to an internal temperature of a minimum of 160 degrees F when tested with an instant read meat thermometer.
To serve with pasta, boil 1 pound of your pasta of choice in salted water 1 minute shy of the package directions. Drain well and pour the pasta into the pot with the meatballs and sauce. Garnish with a little torn fresh basil leaves, if desired. Serve with Parmesan cheese.
