2 1/2 pounds red potatoes
1/2 cup mayonnaise
1/4 cup sour cream
1 tablespoon red wine vinegar
1/2 teaspoon salt
1/4 teaspoon pepper
4 to 5 slices bacon, cooked and crumbled
4 green onions, chopped
3 ounces crumbled blue cheese
Peel the potatoes, then cut each one into eighths. Place the potatoes in a large pot, cover with water, and boil until tender, about 20 minutes. Drain potatoes and set aside to cool.
In a measuring cup, whisk together mayonnaise, sour cream, vinegar, salt and pepper until smooth.
To serve, place the potatoes in a large serving bowl. Add bacon, chopped green onions and blue cheese. Fold in dressing (you may not want to use it all) and gently stir. Refrigerate until ready to serve.
