We ranked the sandwiches according to flavor, freshness, and structure. Believe it or not, the egg salad sandwich was a clear winner. Called the Simply Egg Salad Sandwich, this sandwich certainly lived up to its name as it consisted of nothing more than egg salad between two slices of white bread. Even the egg salad was a basic combination of eggs, mayo, and Dijon mustard. The creamy, savory eggs with that sweet, tangy Dijon made for a well-balanced taste.
