Bring a large pot of salted water to a rolling boil. Add the tri-color rotini pasta and cook for 8 to 10 minutes until al dente, then drain and rinse under cold water.

In a mixing bowl, combine mayonnaise with ranch seasoning to your taste using a whisk for a smooth consistency.

Combine the cooled rotini pasta with chopped lettuce, halved tomatoes, diced turkey, ham, bacon, and cheddar cheese in a large bowl.

Drizzle the ranch dressing over the mixed ingredients and gently toss to coat.

Cover and refrigerate the salad for at least 1 hour before serving to allow the flavors to meld.
