Dice the chicken breast into bite-sized pieces and season evenly with sea salt and black pepper.
Heat avocado oil in a large skillet or wok over medium-high heat until it begins to shimmer.
Add the chicken to the pan and cook until golden brown and cooked through, then remove and set aside on a plate.
In the same pan, add the broccoli, sliced bell peppers, and snap peas, sautéing for 3-4 minutes until tender-crisp.
Stir in the minced ginger and garlic, cooking for one minute until the aromatics are fragrant.
Return the cooked chicken to the pan and pour in the tamari, honey, and toasted sesame oil.
Toss everything together for another minute to coat the ingredients in the glossy, savory glaze.
Garnish with sesame seeds and serve immediately while hot.
