Cook the pasta in a large pot of salted water according to package instructions until al dente, 8-10 minutes. Drain and rinse under cold water.

Prepare the vegetables and meats by combining chopped lettuce, halved tomatoes, crumbled bacon, and diced turkey and ham in a mixing bowl.

Make the dressing by whisking together ranch dressing, mayonnaise, and ranch seasoning in a separate bowl until smooth.

Combine the cooled pasta with the mixed vegetables and meats. Add the dressing and fold until well-coated.

Adjust seasoning as necessary, then refrigerate for at least one hour to meld flavors.

Serve chilled, garnished with shredded cheese if desired.
