Make the dressing by adding all of the ingredients to a small bowl and whisk till it comes together and you can see any oil drops.
Bring a pot of water to a boil, carefully lower in 4 large eggs into the water with a spoon. Boil for 8 minutes. Remove the eggs from the pot and place them in a bowl of cold water to chill. Once the eggs are cool, peel and chop them.
Meanwhile, add bacon to a large skillet over medium heat. Cook until crispy, about 2-3 minutes on each side. Transfer bacon to a paper towel-lined plate and let cool. Drain all but one tablespoon of bacon grease from the skillet. You will use the bacon grease for cooking the chicken. Once the bacon has cooled, chop and set aside.
Cut the chicken breast into 1 inch pieces, salt, and pepper them. Heat 1 tablespoon of the bacon grease over medium heat. Add chicken to the skillet. Cook for 4 minutes, turnover, and cook for another 4 minutes, or until the chicken has cooked through. Once done, transfer chicken to a large plate.
To assemble the salad, place 2-3 cups of lettuce in a bowl. Top with sliced egg, bacon, chicken, tomatoes, avocado, and blue cheese. Then top with dressing.
