Preheat the oven to 400 degrees F. Line a large baking sheet with parchment paper. Place the first 9 ingredients in a large bowl and mix to combine. Moisten your hands with cold water. Roll the meat into 1 1/2” balls and set on the baking sheet. Roast the meatballs for 25 minutes, or until cooked through.
Place the sauce and water in a large pot, set over medium to medium-high heat, and bring to a simmer. When the meatballs are cooked, drain well, and then add them to the sauce. Simmer the meatballs, partially covered, for 15 to 20 minutes. Serve the meatballs on top of your favourite pasta.
