Egg salad sandwiches are wonderful from time to time. I like keeping my egg salad simple. Here is what I do.
Add eggs to a pan of water then heat water until water just begins to boil, remove from stove, cover and set timer for 15 minutes. There is a lot of different discussions about how to hard cook eggs. This is what works for me. Once timer goes off, remove lid, drain water from pan and add cold water. You want the eggs to cool off to stop the cooking process. Peel eggs and place in a bowl.
Mash eggs with a potato masher. Mash until you get the consistency that you want. Add your favorite mayonnaise and mix.
Add salad to bread or a salad of greens. Add salt and pepper to your taste.
