Mrs. Z's Egg Salad Sandwiches

Yesterday Kathleen Z. treated us to her mother-in-law's egg salad sandwiches on croissants -- a very nice variation on the standard egg salad. This is how she makes it (amounts are suggestions only and can be varied to taste). Kathleen made hers with chicken and it was very, very good.
