Stir in the tomato paste, 2/3 cup of the milk, the salt, pepper, and oregano, reduce to a simmer, and cook,stirring frequently until the milk has been absorbed.

Meanwhile, cook the pasta in a large pot of boiling water until just tender.Drain well.
Transfer the sauce to a large bowl, add the pasta, the parsley, if desired, and the Parmesan and toss to combine all.
Spoon the Penne Bolognese into 4 bowls and serve with additional Parmesan cheese, if desired.
