Parmesan Peppercorn Salad Dressing

The Liberty Inn in Beloit has the best house dressing. I have tried to replicate it here and Randy gave it a thumbs up. I don't know if I agree that it is quite as good as the restaurant's, but maybe that has more to do with the fact that I am being served a salad with the dressing, as opposed to having to whip it up myself. Food always tastes better if someone else does the cooking, right?

Parmesan Peppercorn Salad Dressing

1 cup buttermilk

1/2 cup reduced fat sour cream

3 Tbl. low fat mayo

3 Tbl. grated parmesan cheese 

3/4 tsp. dried parsley

3/4 tsp. dried chives

1/2 tsp. dried oregano

1/2 tsp. garlic powder

1/2 tsp. salt

1/4 tsp. freshly ground black pepper

Combine all ingredients and whisk well, or combine in a shaker container and blend by shaking it. Serve with additional freshly ground pepper over the top. Keep refrigerated and shake to blend well before serving. Best if used within 3-4 days.
