For sauce, in a large saucepan cook ground meat, onion, and garlic until meat is brown. Drain off fat. Stir in un-drained tomatoes, Italian seasoning, sugar, salt, and pepper. Bring to boiling; reduce heat. Simmer, uncovered, about 40 minutes or until most of the liquid is evaporated, stirring occasionally.
Meanwhile, cook pasta according to package directions; drain. Return to saucepan; cover and keep warm.
Gradually stir the whipping cream into the sauce. Heat through, stirring constantly. Remove from heat, stir in parsley.
Transfer cooked pasta to dinner plates or a warm serving platter. Spoon the sauce over pasta.
