For the Sauce:
- 3 tablespoons extra-virgin olive oil
- 1 large onion, finely diced
- Kosher salt
- 2 tablespoons tomato paste
- 1 pound ground pork shoulder
- 2 teaspoons red pepper flakes
- 2 28-ounce cans whole San Marzano tomatoes, crushed by hand
For the Meatballs:
- 2 pounds ground pork shoulder
- Kosher salt
- 3 to 4 pickled hot cherry peppers, minced, plus 2 to 3 tablespoons pickling liquid from the jar
- 4 slices white bread, finely chopped
- 3 large eggs, lightly beaten
- 2 tablespoons extra-virgin olive oil
- Polenta, for serving (optional)
Make the sauce: Heat the olive oil in a large pot over medium heat. Add the onion and 2 teaspoons salt; cook, stirring, until soft, about 5 minutes. Stir in the tomato paste and cook, stirring, until the oil is red, 2 to 3 minutes. Add the pork and red pepper flakes and cook, stirring, until the meat is cooked through, about 10 minutes.
Meanwhile, make the meatballs: Preheat the oven to 450 degrees F. Mix the ground pork, 1 tablespoon salt, the cherry peppers and their pickling liquid, the bread and eggs with your hands until combined. Roll into 24 golf ball-size meatballs.
Coat a rimmed baking sheet with the olive oil, then put the meatballs on it and bake until firm and cooked through, about 14 minutes; let cool 5 minutes on the baking sheet.
Divide the meatballs among bowls and top with the sauce. Serve with polenta, if desired.
