Dice the chicken breast into bite-sized cubes and place them in a bowl.
Toss the chicken with arrowroot powder, sea salt, and black pepper until evenly coated.
In a small jar, whisk together the coconut aminos, honey, minced ginger, and minced garlic to create the teriyaki sauce.
Heat the sesame oil in a large non-stick skillet over medium-high heat.
Add the chicken to the skillet and sear until golden brown and cooked through, approximately 6 minutes.
Add the broccoli florets to the pan with a tablespoon of water, then cover with a lid for 2 minutes to steam until vibrant green.
Remove the lid and pour the teriyaki sauce over the chicken and broccoli.
Stir constantly for 1-2 minutes until the sauce thickens into a glossy glaze.
Serve the crispy chicken and broccoli immediately over a bed of warm brown rice.
