Pat the chicken breast dry with paper towels and cut into bite-sized pieces, then toss in a bowl with arrowroot powder, sea salt, and black pepper until evenly coated.
In a small glass jar, whisk together the honey, tamari, minced garlic, grated fresh ginger, and toasted sesame oil to create the stir-fry glaze.
Heat the avocado oil in a large skillet or wok over medium-high heat until shimmering.
Add the chicken in a single layer and sear for 3-4 minutes per side until golden brown and crispy, then remove the chicken from the pan and set aside.
In the same pan, add the broccoli florets and sliced red bell pepper with a splash of water, covering with a lid for 2 minutes to steam until vibrant and tender.
Return the crispy chicken to the pan and pour the honey-garlic sauce over the mixture.
Toss everything together for 1-2 minutes over medium heat until the sauce thickens and coats every piece with a glossy finish.
