First you boil your eggs, of course, unless you like really runny egg salad. The trick to perfect boiled eggs is starting them in cold water, bringing them to a boil, turn off the burner and set them aside and cover them. If you keep boiling them, they will have green yokes. Nothing turns people off like serving them green egg salad. Leave them there stewing in their own juices for about 25 minutes. This angers the eggs, but what can a person do?
After peeling them, and this again is my preference. You may like eggshell in your egg salad, but I wouldn't recommend it. Then I take an old potato masher and start mashing those eggs until they are fine. We like our egg salad a little more chunky so I don't mash mine as fine as some.
Then comes the fun part. Making your sandwich. I used multi-grain sandwich thins toasted and spread the egg salad thinly on it as I don't like alot of filling.
