Begin by bringing a large pot of salted water to a rolling boil. Add the tortellini and cook according to package instructions, typically around 3-5 minutes for fresh tortellini or longer for frozen. Once cooked, drain the tortellini and rinse it under cold water to stop the cooking process.

While the tortellini cools, wash and chop all the vegetables. Toss them into a large mixing bowl along with the finely chopped parsley.

Add the cooled tortellini to the bowl containing the vegetables. Pour in the creamy ranch dressing and sprinkle in the shredded Parmesan cheese. Gently toss the ingredients together.

Cover the mixing bowl and refrigerate the salad for at least 2 hours, or overnight. Chilling allows the flavors to meld beautifully.

Once chilled, give the salad a gentle stir and adjust the dressing if needed. Serve in a chilled bowl with an extra sprinkle of Parmesan.
