1. Combine all ingredients. You may add more mayonnaise. Some salad dressings and mayonnaise are thick and you could add water to thin them.
2. Refrigerate a few hours before eating.
Note: You can add diced cheese, diced ham, peas, diced green peppers, or other sweet vegetables.
Tip: You could substitute marinated cucumbers for celery. Just slice young, small cucumbers, and let them marinate in water with a teaspoon of salt and 1/8 cup of vinegar for a few hours. The cucumber slices retain their crispness and possess a little tartness.
