This tastes just like the sauce you get on your hamburgers at the golden arches.

1/3 cup creamy French dressing
1 cup mayonnaise
1/4 cup sweet pickle relish
1 tablespoon granulated sugar
1 teaspoon dried onion
1/4 teaspoon pepper

Mix all ingredients together well. Store in jar in refrigerator for up to 3 months. Serve with hamburgers.
