Add the pasta to boiling salted water, and cook according to the instructions on the box. Five minutes after you’ve added in the pasta, pour the peas into the pasta and water.
Once pasta is cooked, drain both the peas and pasta. Put the dry pan back on the heat with cream, ham and Parmesan. Cook until warmed through, stirring occasionally.
Add the pasta and peas back in, tossing everything together well.
