Mash the cooled hard-boiled eggs on a cutting board and then transfer it to a large bowl.
Mix in the mayo, mustard, hot sauce, chives, and season with salt and pepper. Mix until well combined.
Serve the egg salad on toasted buns with crispy bacon and cheese and enjoy!
Notes
You can prepare the egg salad ahead of time, but it's best to assemble the sandwiches just before serving. If you assemble them in advance, the bread can become soggy.
