Step 1 Combine mince, onion, breadcrumbs, half the basil, and parmesan in a large bowl. Roll tablespoons of mixture into balls (about 32) and place on a large plate. Cover and chill mixture until required.

Step 2 Bring tomato sauce and 1 cup water to the boil in a large, deep saucepan. Add meatballs and cook, shaking pan occasionally, for 15-20 minutes or until meatballs are cooked through.

Step 3 Meanwhile, cook pasta in a large saucepan of boiling water following packet instructions. Divide pasta among four serving plates. Top with meatballs and sauce. Sprinkle with remaining basil. Serve with a large green salad.
