Heat the olive oil in a frying pan.
Add the ground pork, breaking up lumps. Cook over medium heat until the meat is no longer pink.
Add the garlic, onion, salt, sugar, pepper and chili. Cook over medium heat, with occasional stirring, until the meat is browned and the onion bits and garlic have started to caramelize. Don’t short cut this step — it is the browning and caramelizing that will really give the meat the sausage flavor.
Add the chopped Chinese broccoli and olives. Cook just until heated through.
Throw in the cooked spaghetti. Toss to coat every noodle with the now very tasty mixture of olive oil and pork fat.
Divide the pasta among three dishes, sprinkle with cheese and serve.
