Pat the chicken breast dry with a paper towel and cut into bite-sized cubes.
Season the chicken evenly with the sea salt and black pepper.
In a small bowl, whisk together the honey, tamari, minced garlic, and grated fresh ginger to create the glaze.
Heat the avocado oil in a large skillet or wok over medium-high heat until shimmering.
Add the chicken to the skillet in a single layer and sear for 3-4 minutes until golden brown and cooked through.
Remove the chicken from the pan and set aside on a plate.
Add the broccoli florets and sliced red bell pepper to the same skillet, adding a splash of water if needed to steam-fry for 3 minutes until tender-crisp.
Return the chicken to the skillet and pour the honey-garlic glaze over the mixture.
Toss everything together for 1-2 minutes until the sauce thickens and coats the chicken and vegetables beautifully.
Garnish with sesame seeds and serve immediately.
