Bring a large pot of salted water to a boil.

Trim the thick stems from the broccoli rabe and cut the stalks in half if they're too long. Rinse well and add to the boiling water for 5 minutes.

Once the broccoli rabe is cooked, use tongs to remove it and rinse under plenty of cold water. Let it drain well. Do NOT discard the cooking water—use the same water to cook the pasta according to the package instructions.

In a large skillet or wok, add the sausage sliced as thinly as possible and sauté in a little olive oil. Once cooked, transfer the sausage to a bowl and set aside.

Add the broccoli rabe and sausage back to the skillet, then pour in 1/4 cup of the pasta cooking water.

Bring to a simmer, then add the cooked pasta.

Serve hot with Parmesan cheese and freshly ground black pepper. Enjoy!
