Roasted Potato Salad

I'm bringing this to the food blogger potluck tomorrow.  Hopefully it'll go over well!

3 lbs potatoes, peeled, cubed, roasted

4 cloves garlic, oven roasted

1/2 lb bacon

1 c sour cream
1/2 large onion, diced
1/2 lb green beans, de-stemmed, chopped into 1 in segments
2 green onions, chopped
1/4 c parsley, chopped
salt+pepper to taste
extra virgin olive oil

Set oven to 400.  Toss potatoes with salt, pepper, and olive oil.  Coat the garlic cloves with olive oil as well.  Roast the potatoes and garlic in the oven on a large sheet pan for ~30 minutes, or until the potatoes are easily pierced with a knife.  Meanwhile, render the fat from the bacon and cook it until crisp.  Remove the bacon and chop.  Set aside.  Remove all but ~1 T bacon grease from the pan.  Saute onions with a pinch of salt until browned.  Remove the onions.  Add in an additional 1 T of the bacon grease and then add in the green beans and a pinch of salt.  Cook until tender crisp.  Squeeze out the garlic from the 4 cloves.  Mash it up and mix with the sour cream.  In a large bowl, gently combine all ingredients.  Season with salt and pepper and taste for seasoning.
