In a small bowl, whisk together the coconut aminos, honey, grated fresh ginger, and toasted sesame oil to create the teriyaki glaze.
Season the cubed chicken breast 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 cook until golden brown and cooked through, approximately 6 to 8 minutes, then remove the chicken and set it aside on a plate.
In the same skillet, add the broccoli florets, sliced red bell pepper, snap peas, and minced garlic, sautéing for 3 to 4 minutes until the vegetables are crisp-tender and vibrant.
Return the cooked chicken to the skillet and pour the prepared teriyaki glaze over the chicken and vegetables.
Toss everything constantly for 1 to 2 minutes until the sauce thickens slightly and creates a glossy coating over the ingredients.
Transfer to a plate and garnish with sesame seeds for a delicate crunch before serving.
