I love egg salad, and while I usually like to enjoy it all on its own, this time I served it as a an additional component to a classic BLT sandwich. I layered bacon, lettuce, and tomato on a baguette with my basic egg salad recipe, but I added one surprise: avocado.
In a medium bowl using a fork and knife, quarter each of the eggs and then continue to slice through them until they're broken down into little pieces. Add the mayonnaise and mustard and stir with a fork, lightly mashing as you go. You want the egg yolk and the mayonnaise-mustard to become a cohesive binder for your egg salad, so continue to mix until you get this result. Next add the celery, chives, and lemon juice, and mix to combine. Season with salt and pepper to taste, and then gently fold in the diced avocado. Refrigerate the egg salad until ready to use.
To assemble, divide the egg salad evenly among the bottom pieces of the baguette. Top each piece with 2 slices of tomato, a couple of slices of bacon, and a slice of lettuce. Add the top half of the baguette and serve.
