Carefully place the eggs in the bottom of a large pan.
Add the frozen blueberries on top of the eggs and add just enough cold water on top to cover the eggs.
Place the pan on the stovetop over high heat and bring to a boil.
When the water starts to boil, remove the pan from the heat, cover with a lid, and allow to sit for 10 minutes.
Carefully roll the eggs on the counter to crackle the egg shells. You want to be gentle so you have small cracks and you don't loose big chunks of the eggshell.
Gently place the eggs in a large food storage container with a lid. Transfer the blueberries and as much of the blueberry juice as you can to cover the eggs in the container. You can dump the remaining liquid down the sink. Place the lid on the container and store in the fridge for up to 24 hours.
The next day, remove the hard boiled eggs from the blueberry water and carefully peel the shells off.
Carefully slice each egg in half lengthwise.
Scoop out the egg yolks and place them in a bowl.
If necessary, rinse off the egg yolks and place on a paper towel to dry.
To the egg yolks, add the avocado, the mayonnaise, lemon juice, and salt and pepper to taste. Mix until well combined.
Carefully spoon the avocado mixture into each egg half.
Slice the olives in half, and then into thin strips. I got 6 strips from each olive half.
Place the olive strips in the center of each egg, making it look like an eye.
Serve and enjoy!
