Bring a large pot of salted water to a rolling boil, then add the rotini pasta. Cook according to package directions, usually around 8–10 minutes, until al dente. Drain and rinse under cold water.

In a large mixing bowl, pour in your ranch dressing. Whisk until smooth, and add any desired flavorings like garlic powder or fresh herbs.

Once the pasta is cool, add it to the bowl with the ranch dressing along with the cooked and crumbled bacon and chopped vegetables. Toss until well coated.

Cover the bowl and chill in the refrigerator for at least 2 hours, or overnight for best flavor.

Before serving, stir the salad well and transfer it to a serving platter or bowls.
