Thaw the peas in a colander by running cold water over them or allow them to thaw slightly while you prepare the ingredients.
In a large bowl, whisk together the mayonnaise, sour cream, apple cider vinegar, sugar, salt, and pepper until well combined.
Mix the remaining ingredients well in a large bowl.
Cover and refrigerate until ready to serve.
Notes
The creamy dressing will thicken as it chills.I prefer to use frozen peas, which I thaw slightly before adding to the salad.If desired- Place peas in a colander, run cold water over the top, and thaw slightly before adding them to the bowl.
