This egg salad made with olive oil mayonnaise and fresh herbs is incredibly delicious - to make the best Egg Salad Sandwich, use crunchy toast or eat it solo!
First for the pickled onions, dice half a red onion into small pieces. In a small jar, combine the onions with a pinch of salt, and enough white wine vinegar to cover the onions. Let sit while you prep, or for a few hours in the fridge.
Next, chop your herbs into small pieces, and then chop up the hard-boiled eggs as well.
In a bowl, combine the diced eggs, herbs, 2 tbsp of pickled onions (drain against the side of the jar while scooping out), a bit of salt & pepper, mayo, & Dijon mustard.
To assemble a sandwich, layer a piece of butter lettuce over a piece of bread, and add a portion of the egg salad on top, then add the other piece of bread on top, slice, and enjoy!
