SPAGHETTI AND MEATBALLS

Steps:

• Make sauce:
• Drain tomatoes, reserving juice in a large bowl. Crush tomatoes with your hands and add to juice.
• Cook onions in oil in pot over medium heat, stirring occasionally, until softened, about 10 minutes. Add garlic and cook, stirring occasionally, until softened, about 2 minutes. Stir in tomatoes with their juice, 4 teaspoons salt, and 1 teaspoon pepper. Simmer sauce, uncovered, stirring occasionally, until slightly thickened, 45 minutes to 1 hour. Season with salt.
• Make meatballs while sauce simmers:
• Cook onions in extra-virgin olive oil in a 12-inch heavy skillet over medium heat, stirring occasionally, until softened, about 10 minutes. Add garlic and cook, stirring occasionally, until softened, about 3 minutes. Transfer to a large bowl to cool.
• Soak bread in milk in another bowl until soft, about 5 minutes. Firmly squeeze bread to remove excess milk, discarding milk.
• Stir together cooled onion mixture, bread, eggs, parmesan, parsley, oregano, lemon zest, 5 1/2 teaspoons salt, and 1 1/2 teaspoons pepper until combined. Add meats to bread mixture, gently mixing with your hands until just combined (do not overmix).
• Form meat mixture into about 70 (1 1/2-inch) balls with dampened hands, arranging meatballs on 2 large baking sheets or in shallow baking pans.
• Heat olive or vegetable oil (1 cup) in a 12-inch heavy skillet (preferably nonstick) over medium-high heat until hot but not smoking, then brown meatballs in 4 or 5 batches (without crowding), turning frequently, about 5 minutes per batch. Return to baking sheets.
• Add meatballs to sauce and gently simmer, covered, stirring occasionally, until cooked through, 20 to 30 minutes. (If pot is not large enough, divide meatballs and sauce between 2 pots.)
• Prepare pasta:
• Cook spaghetti in 2 batches in pasta insert in boiling salted water (3 tablespoon salt for 6 qt water) until just al dente, draining and tossing each batch with some of sauce in a large serving dish.
• Serve with meatballs, remaining sauce, and grated cheese.
