Fill a medium or large pot halfway with water and bring to a boil.
Add the pasta and cook until al dente, about 8-10 minutes. Drain and rinse thoroughly under cold water.
While the noodles are cooking, shred your lettuce if it isn't already shredded, and cut your tomatoes in half.
Transfer the cooked noodles and ranch dressing to a bowl and mix well to coat the pasta.
Add the chicken, lettuce, tomatoes, cheese, and bacon, then gently toss everything together.
Cover and refrigerate for 1 hour, or until ready to serve.
Notes
Double this recipe if feeding a crowd. Rinse pasta with cold water to stop cooking. Chill at least 1 hour for best flavor. Add extra ranch dressing if salad seems dry after storing.
