Ingredients:
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

In a small bowl, combine all the ingredients: mayonnaise, French dressing, sweet pickle relish, minced white onion, white vinegar, sugar, and salt.
Stir well until all the ingredients are fully incorporated and the sauce is smooth.
