Pat the chicken breast dry with a paper towel and season both sides evenly with sea salt, black pepper, and dried oregano.
Heat the extra virgin olive oil in a large skillet over medium-high heat until it begins to shimmer.
Place the chicken in the skillet and sear for 5 to 6 minutes per side, or until the internal temperature reaches 165 degrees Fahrenheit and the exterior is golden brown.
Remove the chicken from the pan and set it aside on a plate to rest.
In the same skillet, add the minced garlic and asparagus spears, sautéing for 4 to 5 minutes until the asparagus is tender-crisp and slightly charred.
Stir in the lemon juice and lemon zest, using a wooden spoon to scrape up any flavorful browned bits from the bottom of the pan.
Slice the rested chicken into strips and return it to the skillet, tossing briefly to coat in the lemon-garlic sauce.
Garnish with freshly chopped parsley and serve immediately.
