Using a large skillet, heat the avocado oil on medium heat.
Add the chicken to the skillet and lightly season with salt and pepper. Cook until the chicken reaches an internal temperature of 165 F. Set aside.
Add more oil to the pan if needed and saute the asparagus with more salt and pepper for about 5-7 minutes or until softened and lightly crisp. Set aside.
Reduce the heat slightly and add the minced garlic to the pan. Cook until fragrant.
Add the broth, lemon juice, coconut aminos, and arrowroot starch to the pan and stir for about 2-3 minutes or until the sauce lightly thickens.
Add the chicken and asparagus back to the pan and cook for another 2 minutes to reheat.
Serve topped with green onion and season further to taste.

Notes
To prep the asparagus, start by chopping off the thick white ends and discarding. I recommend chopping the rest of the asparagus on a bias into 1/2"-3/4" pieces.
