Season the pork, working the seasoning in with your hands, then shape into small meatballs. Heat the oil in a large pan, add the meatballs and cook for 5 mins, until golden brown all over. Push to one side of the pan and add the onion and peppers. Cook for a further 5 mins, stirring now and then, until the veg has softened, then stir in the garlic and paprika. Stir everything around in the pan for 1 min, then add the tomatoes. Cover with a lid and simmer for 10 mins.
