In a large bowl combine the ranch dip, sour cream, mayo, salt and pepper to taste.
Add in the remaining ingredients to the dressing mixture: elbow noodles, cheese, peas, bacon and red onion.
Stir until combined thoroughly.
Serve immediately or chill until ready to serve.
Notes
Make sure the pasta is fully cooled before mixing it with the dressing—this helps prevent the sauce from becoming too thin and keeps the salad creamy and flavorful.
