1/2 cup mayonnaise
2 tablespoons catsup
1 tablespoon vinegar
2 teaspoons sugar
2 teaspoons sweet pickle relish
1 teaspoon finely minced white onion
1/8 teaspoon salt
Black pepper to taste

Combine all of the ingredients in a small bowl.

Stir well.

Pour dressing into a covered container and refrigerate for several hours, stirring occasionally, allowing the sugar to dissolve and the flavors to marry

This is best made the day before serving.
