Buttermilk Ranch Salad Dressing

I got this recipe from Mike's sister, Dianna Tangren. I like lots of flavor, so I go a little heavy (heaping) on the onion salt and garlic.

2 cups buttermilk

2 cups mayonnaise (I use a mixture of regular and low-fat)

1 heaping teaspoon onion salt

1 tsp. Accent

1/4 heaping teaspoon garlic powder

3/8 tsp. pepper

1/2 tsp. salt

1 tsp. dried parsley

Mix all ingredients together.
