Follow these simple steps to create your Chicken Bacon Ranch Pasta:

1. Cook the Pasta: Boil a large pot of salted water. Add the rotini pasta and cook according to package instructions until al dente. Drain and set aside.
2. Prepare the Chicken: While the pasta cooks, heat a large skillet over medium heat. Add the diced chicken and season with salt and pepper. Cook until warmed through, about 3-5 minutes.
3. Combine Ingredients: Once the chicken is cooked, reduce the heat to low. Add the cooked pasta, crumbled bacon, ranch dressing, and shredded cheddar cheese to the skillet. Stir well to combine.
4. Heat Together: Continue stirring the mixture for another 3-5 minutes until everything is heated and the cheese is melted.
5. Add Tomatoes: If using, stir in the diced tomatoes for added freshness.
6. Garnish and Serve: Remove from heat and sprinkle with chopped fresh parsley for a lovely finish. Serve immediately while hot.

These easy steps make it simple to create a hearty meal that everyone will enjoy.
