1/2 cup mayonnaise
2 tablespoons French dressing
4 teaspoons sweet pickle relish
1 tablespoon finely minced white onion
1 teaspoon white vinegar
1 teaspoon sugar
1/8 teaspoon salt

Combine all of the ingredients in a small bowl. Stir well. Place sauce in a covered container and refrigerate for several hours, or overnight, so that the flavors blend. Stir the sauce a couple of times as it chills. Makes about 3/4 cup.
