Pat the chicken breast dry with a paper towel and cut into 1-inch cubes.
In a small bowl, toss the chicken with arrowroot powder, sea salt, and black pepper until evenly coated.
Heat the avocado oil in a large skillet over medium-high heat and add the chicken in a single layer.
Cook the chicken for 5-7 minutes, turning occasionally, until the edges are golden and crispy.
While the chicken cooks, whisk together the honey, tamari, minced garlic, and grated ginger in a small jar.
Pour the sauce over the crispy chicken and simmer for 2 minutes until the glaze becomes thick and glossy.
Steam the broccoli florets until tender-crisp and warm the pre-cooked brown rice.
Divide the rice into a bowl, top with the honey-garlic chicken and broccoli, then garnish with sesame seeds.
