Add porcini liquid to the meat and cook for 1 minute to evaporate. Add broth and cook for 2 minutes. Add marinara and wine. Reduce heat and simmer for 3 to 4 minutes. Stir in the parsley.
Note: At the last moment before serving, add a sprinkle of Parmesan into the sauce to help it thicken. Add some reserved pasta water, as necessary, if the sauce appears too dry. Top with remaining Parmesan.
