Egg Salad Sandwich

This Egg Salad Sandwich is a family favorite with a twist. We’ve used eggs, mayonnaise, Dijon mustard, onion, and capers to give this quick dish a unique spin on the classic.

The classic egg salad sandwich has been one of my son’s favorite meals since he was old enough to chew. My husband has been making it for him for almost 18 years, and the recipe is almost always the same. Eggs, mayo, mustard, pickles or relish, and onions on some form of bread.

For a while, my husband opted for a healthier option and lightened it up with a little less mayonnaise, used lettuce wraps instead of bread, or omitted the bread entirely. Regardless of how you enjoy it, this egg salad sandwich is sure to be a family favorite!
