Prepare meatballs by combining beef mince, egg, parsley, garlic and cracked pepper in a large bowl. Using wet hands, roll tablespoons of the mixture into balls.
Spray a large non-stick frying pan with olive oil and set over medium-high heat. Cook the meatballs for 4-5 minutes or until browned. Remove meatballs from the pan.
Reduce heat to medium, add spray olive oil, onions and carrots to the pan saute for 1-2 minutes, or until just softened. Add the tomatoes, chopped tomatoes and meatballs to the pan and bring to the boil. Reduce heat and simmer for 10-15 minutes or until the sauce is reduced and meatballs are cooked through. Stir through basil leaves.
Meanwhile, place spaghetti in a large saucepan of boiling water and cook for 7-9 minutes or until al dente. Drain and serve spaghetti with meatballs, and salad.
