Cook the pasta according to directions on the box. Drain.
While pasta is cooking, dice the onion and finely mince the garlic.
Heat oil in a skillet over medium heat, then add Italian sausage and onion and cook until the meat is no longer pink. Drain the sausage. Add the garlic and cook another minute or two.
Drain the tomatoes well and coarsely chop them. Add cream, tomatoes, salt, and pepper to the sausage mixture.
Combine pasta with the sausage/tomato mixture.
Garnish with parsley, if desired.
Enjoy!
