Pat the chicken breast dry with a paper towel and season both sides evenly with sea salt and black pepper.
In a small mixing bowl, whisk together the fresh orange juice, orange zest, coconut aminos, honey, minced ginger, and minced garlic until well combined.
Heat the avocado oil in a large stainless steel or cast iron skillet over medium-high heat until shimmering.
Place the chicken breast in the skillet and sear for 5 to 6 minutes per side until a golden-brown crust forms and the internal temperature reaches 165 degrees Fahrenheit.
Remove the chicken from the skillet and set it aside on a plate to rest.
Add the trimmed asparagus spears to the same skillet and sauté for 3 to 4 minutes until they are bright green and crisp-tender.
Pour the orange sauce mixture into the skillet with the asparagus and simmer for 1 to 2 minutes until the liquid reduces into a thick, glossy glaze.
Slice the chicken into strips, return it to the pan, and toss everything together to coat thoroughly in the zesty sauce before serving.
