Dad's Favorite Salad Dressing

Put mayonnaise into a small bowl and mix until smooth. Add sugar and mix. Slowly add red wine vinegar & mix together. We like it on a salad of lettuce, tomatoes, cucumbers, peppers, celery, etc. and hard–boiled eggs cut up on top. Very good with shrimp on top of salad also. Add the dressing and enjoy!! We love it.
