Pat the chicken breast dry with a paper towel and cut into bite-sized cubes.
In a small bowl, toss the chicken cubes with arrowroot powder, sea salt, and black pepper until evenly coated.
In another small bowl, whisk together the minced garlic, grated ginger, honey, tamari, and sesame oil 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 cook for 5-6 minutes, turning occasionally, until golden brown and cooked through.
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.
Cover and steam the vegetables for 2-3 minutes until they are bright green and crisp-tender.
Return the chicken to the pan and pour the honey-garlic glaze over the mixture.
Toss everything together for 1 minute until the sauce thickens and becomes sticky, coating every piece.
Serve the stir-fry immediately over the warm cooked jasmine rice and garnish with sesame seeds.
