Pat the chicken breast dry and cut into bite-sized pieces.
In a small bowl, toss the chicken with arrowroot powder, sea salt, and black pepper until evenly coated.
In a separate small jar, whisk together the minced garlic, grated ginger, honey, tamari, and toasted sesame oil to create the glaze.
Heat the avocado oil in a large skillet or wok over medium-high heat.
Add the chicken to the skillet in a single layer and sear until golden brown and cooked through, about 5-6 minutes.
Remove the chicken from the pan and set aside.
Add the broccoli florets and sliced red bell pepper to the same pan with a splash of water, covering for 2 minutes to steam-fry until vibrant.
Return the chicken to the pan and pour the honey-garlic sauce over the mixture.
Toss everything together for 1-2 minutes until the sauce bubbles and thickens into a glossy glaze.
Serve the stir-fry immediately over the warm, fluffy brown rice.
