Bring a pot of water to a boil. Lower the heat so the water is just simmering, then gently lower the eggs into the pot using a skimmer or spoon. Turn the heat back up and boil for 12 minutes.
Once done, transfer the eggs to an ice water bath and let them cool completely, about 15 minutes.
Peel the eggs and slice them in half. Carefully separate the yolks from the whites. Place the yolks in a large bowl and mash them with a fork. Add the mayonnaise, Dijon mustard, and lemon juice to the mashed yolks and mix until smooth.
Roughly chop the egg whites and add them to the bowl along with the tuna, red onion, parsley, chives, and diced dill pickles (or jalapeños). Season with salt and pepper, and gently mix everything until well combined.
Enjoy this creamy, protein-packed egg tuna salad on its own, as a sandwich filling, or in a wrap!
