Bacon Ranch Potato Salad

2 pounds red potatoes, cut into bite-size pieces

1 (16 ounce) container sour cream

1 packet ranch dressing mix

1 1/4 cup cooked bacon, crumbled

1 1/2 cup cheddar cheese

2 bunches green onions, thinly sliced

Place the potatoes into a large pot and cover with salted water.  Bring to a boil over high heat, then reduce heat to medium low, cover and simmer until tender, about 20 minutes.  Drain, then run under cold water until cool.  Use a potato masher and mash about 1/3 of the potatoes.

Combine the sour cream and ranch dressing mix in a small bowl until well blended.  Transfer the potatoes, bacon, cheddar cheese and green onions to a large bowl.  Stir in the sour cream mixture until well coated.  Cover and refrigerate for about 2 hours before serving.
