Slice the chicken breast into bite-sized strips and season with sea salt and black pepper.
In a small bowl, whisk together the tamari, honey, minced fresh ginger, and minced garlic to create the stir-fry sauce.
Heat a large skillet or wok over medium-high heat with the avocado oil until shimmering.
Add the chicken to the pan and sear for 3-4 minutes until golden brown and cooked through, then remove chicken from the pan and set aside.
In the same pan, add the broccoli florets, sliced red bell pepper, and sugar snap peas with a splash of water, covering for 2 minutes to steam-soften.
Remove the lid and stir-fry the vegetables for another 2 minutes until they are bright and crisp-tender.
Return the chicken to the pan and pour the tamari sauce over the mixture, tossing constantly for 1 minute until the sauce thickens and glazes the ingredients.
Remove from heat, drizzle with toasted sesame oil, and garnish with sesame seeds before serving.
