Pat the chicken breast dry and season both sides with sea salt and black pepper.
In a small bowl, whisk together coconut aminos, honey, minced garlic, and grated fresh ginger to create the clean teriyaki sauce.
Heat olive oil in a large skillet over medium-high heat and sear the chicken for 5-6 minutes per side until golden and fully cooked.
Remove chicken from the pan and let it rest for 3 minutes before slicing into thin strips.
In the same skillet, add the green beans and a splash of water, then cover for 3 minutes to steam until vibrant and crisp-tender.
Remove the lid, add the sesame oil and sesame seeds to the beans, and sauté for 1 minute until fragrant.
Pour the prepared teriyaki sauce into the skillet with the beans, add the sliced chicken back in, and toss everything together until the sauce thickens and coats the ingredients.
