Cook the brown rice according to package instructions and set aside.
In a small bowl, whisk together the coconut aminos, honey, grated fresh ginger, and minced garlic to create the teriyaki glaze.
Season the diced chicken breast with sea salt and black pepper.
Heat the avocado oil in a large skillet over medium-high heat and sear the chicken until golden brown and cooked through.
Remove the chicken from the skillet and add the broccoli, sliced bell peppers, and sugar snap peas.
Stir-fry the vegetables for 3-4 minutes until they are crisp-tender, then drizzle with the toasted sesame oil.
Return the chicken to the skillet and pour the teriyaki glaze over the mixture, tossing for 1 minute until the sauce thickens and coats everything evenly.
Serve the chicken and vegetables over the warm brown rice and garnish with sesame seeds.
