In a small glass bowl, whisk together the tamari, toasted sesame oil, rice vinegar, and honey until well combined to create the stir-fry sauce.
Dice the chicken breast into bite-sized pieces and season evenly with sea salt and black pepper.
Heat the avocado oil in a large skillet or wok over medium-high heat until shimmering.
Add the chicken to the skillet and sauté for 5-6 minutes, stirring occasionally, until the pieces are golden brown and cooked through. Remove the chicken from the pan and set aside.
In the same skillet, add the broccoli florets, sliced red bell pepper, and snap peas. Stir-fry for 3-4 minutes until the vegetables are tender yet retain a vibrant color.
Add the minced ginger and garlic to the vegetables and cook for 30-60 seconds until highly fragrant, taking care not to burn the garlic.
Return the cooked chicken to the skillet and pour the prepared sauce over the chicken and vegetables.
Toss everything together for 1-2 minutes until the sauce has thickened slightly and coats every ingredient evenly.
Remove from heat, garnish with freshly sliced green onions, and serve immediately.
