Step 1

Bring a large pot of well-salted water to a boil. Cook the pasta according to package directions until al dente. Drain, toss with the olive oil and set aside to cool.

Step 2

Stir the seasoning mix with the sour cream. When the pasta is cool, toss with the sour cream mixture, chicken, bacon and Parmesan cheese, if using. Chill for at least 1 hour before serving cold.
