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

While the pasta is cooking, prepare all mix-ins: cube the cheddar cheese, dice the tomato, chop the bacon and salami, and dice the turkey or chicken.

In a large mixing bowl, whisk together the mayonnaise and ranch seasoning mix until smooth.

Once the pasta has cooled, add it to the bowl with the dressing. Fold in the cheddar, tomato, bacon, lettuce, salami, and turkey or chicken, mixing gently.

Cover the bowl with plastic wrap and refrigerate the pasta bowl for at least 30 minutes.

Just before serving, give the pasta bowl a gentle toss and add lettuce if prepared separately.
