Start by bringing a large pot of salted water to a rolling boil. Add the tri-color rotini pasta and cook according to package instructions until al dente, around 8-10 minutes. Drain the pasta in a colander and rinse it under cold water.

In a large mixing bowl, combine the cooled tri-color pasta with diced cheddar cheese, crispy bacon, chopped lettuce, diced ham, turkey, and chopped tomato. Drizzle the mayonnaise over these ingredients, followed by the ranch seasoning. Gently toss everything together.

Cover the bowl tightly with plastic wrap and place it in the refrigerator. Allow the salad to chill for at least 6 hours, preferably overnight.

Before serving, give the salad a good stir and adjust seasoning with salt and pepper. Spoon the salad into serving bowls and enjoy.
