Pat the chicken breast dry with paper towels and cut into 1-inch cubes.
In a medium bowl, toss the chicken cubes with arrowroot powder, sea salt, and black pepper until evenly coated.
Heat the toasted sesame oil in a large non-stick skillet over medium-high heat.
Add the chicken to the skillet in a single layer and cook for 5-6 minutes, turning occasionally, until the edges are golden brown and the meat is cooked through.
While the chicken is searing, whisk together the honey, tamari, minced garlic, and grated ginger in a small bowl.
Steam the broccoli florets for 3-4 minutes until they reach a tender-crisp texture and bright green color.
Pour the honey-garlic sauce over the chicken in the skillet and toss for 1 minute until the sauce thickens into a glossy, sticky glaze.
Serve the glazed chicken immediately over the warm jasmine rice with the steamed broccoli on the side.
Garnish with sesame seeds and sliced green onions for a fresh, aromatic finish.
