Cook pasta according to package directions until al dente. Drain and rinse under cold water to cool. Set aside.
While pasta cooks, cook bacon in a skillet over medium heat until crispy, about 8-10 minutes. Transfer to paper towels to drain, then crumble into small pieces.
In a large bowl, whisk together mayonnaise, sour cream, ranch seasoning mix, and apple cider vinegar until smooth.
Add the cooled pasta, crumbled bacon, cherry tomatoes, peas, red onion, and cheddar cheese to the bowl. Toss gently until everything is evenly coated with dressing.
Season with salt and pepper to taste. Cover and refrigerate for at least 1 hour before serving to allow flavors to meld.
