1/2 cup nonfat or low-fat plain yogurt, or 1/3 cup
nonfat or low-fat Greek-style yogurt
1/3 cup low-fat buttermilk
3 tablespoons mayonnaise
1-1/2 teaspoons lemon juice
1 teaspoon Dijon mustard
1/4 teaspoon garlic powder
2 teaspoons dried chives
Salt and pepper
If using plain yogurt, place it in a strainer lined with a paper towel and place the strainer over a bowl. Let the yogurt drain and thicken for 20 minutes.
In a medium bowl, combine the strained or Greek-style yogurt and the rest of the ingredients. Add salt and pepper to taste.
