Put a large skillet over a medium flame and melt the butter.
Add the ham to the pan and sauté until lightly crisp, about 5 minutes.
Add the cream and black pepper to the pan and bring to a simmer. Do not boil the cream or it may curdle.
Cook for about 5 minutes or until the cream begins to thicken.
Shut off the flame and stir in the cheese.
Drop the tortellini into salted boiling water and cook according to the package instructions. Drain and add the tortellini to the pan. Toss over a medium flame for 1 minute.
Serve immediately with an extra sprinkle of grated Parmigiano cheese.
