Add a tablespoon of water at a time until you reach the desired consistency. I used 1/4 cup water.
Salt and pepper to taste.
This recipe makes about a cup of the dressing. I calculated the dressing serving size as one tablespoon so that's where the calorie and nutrition facts come from. Each tablespoon has about 30 calories.
