I first found this recipe on Allrecipes quite sometime ago and it has become a staple in our house. This makes a lot of dressing but in our house it goes quite quickly. If you find the vinegar a bit strong, you may want to scale it back to 1 1/2 quarts. Great for greek salads or any kind of dinner salad. We also use this as a topping for fresh tomatoes in the summertime.
