Heat a frying pan until hot, then add the tomatoes and olive oil and bring to a gentle simmer.
Add the garlic, chilli and half of the basil and cook for 10 minutes, until reduced and thickened. Season, to taste, with salt, freshly ground black pepper and a little sugar.
Place the pork mince, bacon, thyme and parsley into a bowl and mix thoroughly. Season with a little salt and plenty of freshly ground black pepper.
Divide the mixture into 16 and shape each portion into a small ball, using your hands.
Place the meatballs into the tomato sauce and simmer for 5-8 minutes, or until the meatballs are completely cooked through.
Meanwhile, bring a large pan of salted water to the boil. Add the spaghetti and cook according to packet instructions.
Drain the spaghetti, then add to the tomato and meatball sauce. Season, to taste, with salt and freshly ground black pepper and add the remaining basil.
To serve, spoon equal portions of the spaghetti and meatballs into warmed bowls.
