Set sous vide machine to 63C/145F. Once temperature is reached, gently place eggs in the bath for 45 minutes.
In a small bowl, combine avocados, lemon juice and garlic salt. Gently mash ingredients with the back of a fork until creamy.
Remove eggs from sous vide bath with tongs. Immediately place eggs into a bowl of ice water for 5 minutes.
Spread mashed avocado mixture on warm toasted bread, then garnish with red pepper flakes and shaved parmesan. Place sous vide egg and bacon (optional) on top, and enjoy!
(Optional) Preheat oven at 175C/350F. Line a baking sheet with parchment paper and place strips of bacon on it. Bake for 15 minutes, remove from oven and flip the bacon with tongs. Return to oven for another 15 minutes, or until desired crispiness.
High quality ingredients are the key to making this recipe the best it can be. Make sure to pick up fresh bread and hand select perfectly ripe avocados.
