Bring a large pot of water to a rolling boil over high heat. Add the tri-color pasta and cook according to package instructions until al dente, typically 8-10 minutes. Drain and rinse under cold running water.

While pasta cools, prepare the other ingredients: chop cheese, dice tomatoes, ham, and turkey, and cook bacon until crispy.

In a large mixing bowl, combine the cooled pasta, cubed cheese, crumbled bacon, lettuce, diced ham, diced turkey, and tomatoes. Add mayonnaise and ranch seasoning, and fold together gently.

Cover the bowl and refrigerate for at least 6 hours or overnight to allow flavors to meld.

After chilling, stir and adjust seasoning as desired with salt and black pepper. Serve in a bowl.
