I've tried many variations of egg salad sandwiches over the years but I always return to my basic recipe as follows. Important to use the best ingredients. Try my posted Recipe #330137 recipe. Egg salad sandwich made with store bought mayonnaise is really good but egg salad sandwich made with homemade mayonnaise is worthy of exaltation! I only add dill occasionally and *only* if it's fresh from our herb garden. *Warning*: contains raw egg. --Tasty-- does like a few black olives (chopped) stirred into her egg salad sandwich. I begrudgingly comply...;) Nothin' like indulging the little darlin'!
