Bring a pot of water with your eggs in the pot, to a boil over high heat. Once boiling, turn heat to low and let boil for 8 minutes. As soon as the eggs are ready, remove from hot water directly into an ice bath. Let the eggs sit for just a few minutes and peel. Set aside.
Chop up the hard boiled eggs and place into a mixing bowl. Add some mayonnaise, dijon mustard, mix and taste. Adjust anything as needed. Season with salt and pepper to taste and set aside again.
To make the sandwich: spread some Thousand island dressing on one side of one piece of toasted bread (if you want even more thousand island flavor, spread on one side of both pieces of bread). Add the egg salad, lettuce, pickled red onions and the chips. Gently press the chips down so they crack and stick to the sandwich more. Place one side on top of the other. Repeat and make the second sandwich.
Wrap sandwiches in parchment paper if desired, slice and enjoy!
